J&C Joel Acoustic Brochure by J&C Joel Limited

Sage Music Centre, Gateshead

Since the late 1970s, J&C Joel has been supplying wool serges into performing arts spaces. As well as its blackout and masking properties, its durability, and its cost-effectiveness, the acoustic absorption properties have been an acknowledged asset. More recently we started to measure these qualities objectively, using third-party test facilities to reassure our customers that the drapes and banners they are purchasing from J&C Joel are independently verified to meet their performance requirements.

Over the years we have built up an impressive array of acoustic fabrics, including 7 different constructions of serge ranging from 420gsm to 1,000gsm, bonded wool serge, and heavyweight cotton and synthetic velours. As well as acoustic drapery we have developed different ‘banner’ mechanisms, to vertically deploy absorptive surfaces which allow a venue’s acoustic properties to be fine-tuned to suit the characteristics of the performance.

As well as absorption tests to measure the absorption coefficient, we have conducted insulation tests to measure the sound reduction index on multi-layered drapery. Now that we have around 100 test reports, we felt that it was time to compile them into a single document. We hope that this will prove to be a useful reference tool for acousticians, theatre consultants, venue managers, indeed anyone involved in performance spaces.

We have also included some reference guides on testing methodology and the materials being tested. As our range of fabrics and acoustic devices evolves, we intend to continue to add to this document. We welcome any feedback and suggestions on the range of data we are providing you with. After all, this has been created to assist people to understand more about the potential acoustic attributes of our range

Sample Description Explanation

The layout of sample descriptions on acoustic reports:

(Fabric Type - Acoustic Layers - Fullness - (Weight) - Cavity From the Wall)

The ‘Fabric Type’ refers to the fabric that is being acoustically tested for this article.

‘Acoustic layers’ applies to the layers of the fabric examined in the report. For our Motorised Banners reports, multiple acoustic layers can be bonded & pressed to give the fabric, a larger acoustic absorption coefficient.

The ‘Fullness’ of a drape refers to the amount of fabric, used during manufacture to produce a pleated finish.

The ‘Weight’ stated on the reports refers to the approximate weight of the fabric per square meter.

‘Cavity From the Wall’ is the distance between the fabric and the back wall.

Differentiation of G-Value & Cavity From the Wall

Cavity From the Wall - The test specimen is hung parallel to the room surface. The suffix of the mounting type is the distance in millimetres from the back of the test specimen and the wall.

G-Value - The test specimen is hung parallel to the room surface. The suffix of the mounting type is the distance in millimetres from the face of the test specimen and the wall.

Summary

Tests have been done in SRL's Laboratory at Holbrook House, Sudbury, Suffolk, to determine the random incidence sound absorption coefficient of various types of curtain in accordance with BS EN ISO 354:2003 in all ways apart for the sample areas There were 9m2 where the standard requires a minimum of 10m 2 , therefore these tests are not completely in accordance with the test standard.

From these measurements, the required results have been derived and are presented in both tabular and graphic form in Data Sheets 1 to 9.

The results are given in 1/3rd octave bands over the frequency range 50Hz to 10kHz, which is beyond that required by the test standard.

2.0 Description of Test

2.1 Description of Sample

Tests were performed on various curtains which were hung parallel to the wall in the test chamber. The samples were mounted on a test frame simulating the final install conditions. Airspaces of 100mm, 190mm, 200mm, 260mm, 350mm and 450mm between the face of the curtain and the wall were tested The curtains measured 3m high by 3m wide and were suspended on a st eel pole frame system giving an area of 9m2.

Please note – The area of each test sample was below the minimum 10m2 required by the test standard and tests therefore do not completely comply with the test standard. All other elements of the tests are in accordance with the standard.

Appendix A - Test Procedure

Measurements of Random Incidence Sound Absorption

Coefficients Generally to BS EN ISO 354:2003 - TP14 (Plane Absorbers)

In the laboratory, random incidence sound absorption coefficients are determined from the rate of decay of a sound field in a reverberation room, with and without a test sample installed. The rate of decay is described by the time a sound field takes to d ecay by 60dB, known as the reverberation time.

The reverberation room is constructed from 215mm brick, which is internally plastered with a reinforced concrete roof and floor. The reverberation room is rectangular, measuring 8.3 metres long, 6.7 metres wide and 5.4 metres high. The volume is 300m3, the total surface area, 275m2. From the ceiling hang 10 randomly positioned diffusers, with a total surface area (for one side) of 20m 2. The room is isolated from the surrounding structure by the use of resilient mountings and seals, ensuring good acoustic isolation.

Using at least two omnidirectional loudspeaker positions, broad band random noise is produced in the room using an electronic generator and power amplifier. When the amplification system is switched off, the decay of sound is filtered into one-third octave band widths and the reverberation times measured. This process is repeated for each of six microphone positions and the values arithmetically averaged to obtain a final value for each frequency.

The sample area should normally be between 10m 2 and 15.7m2. This may be larger if it is suspected that the absorption properties will be low. The sample in this instance has an area of 9m 2 and therefore tests are described as generally in accordance with the test standard. The sample is suspended from a pre -assembled rig positioned on the floor of the reverberation room close to one wall. The test rig provides a space between the sample and wall, the depth of which can be varied to simulate speci fic requirements. The procedure of measuring the reverberation times then repeated.

The sound absorption coefficients are calculated from the difference in decay rates for each frequency according to the formula:

s = AT S where



s is the random incidence absorption coefficient

AT is the increase in equivalent sound absorption area of the test specimen (m 2)

S is the area covered by the test specimen (m 2)

The equivalent absorption area of the test specimen is further defined as:

AT =55.3V ( 1 c2 T21 c1 T1 ) -4V(m2 -m1 ) where

It is occasionally found that the absorption coefficient derived in this manner reaches a value greater than unity. This is impossible, by definition, and investigation has shown that this anomaly is due to diffrac tion of the impinging sound waves at the edges of the sample. In practical terms this is insignificant.

Single Layer Banner

Cadenza (Single Layer Banner)

The Cadenza Acoustic Banner is a budget-friendly option within the J&C Joel variable acoustic range. Deploying a single layer of Bonded Wool Serge it achieves a Class B acoustic absorption rating according to EN ISO 11654:1997.

The Cadenza can offer an absorbent area of up to 48m2. With 6m as the maximum width, and 10m as the maximum drop. Custom sizes are available on request.

Works with Bonded Wool Serge*, available in 1,130gsm, 1000gsm, or 840gsm to achieve different acoustic requirements. The standard fabric colour is black, with a range of 10 colours available on 1,000gsm, custom colours available subject to MOQ. *100% recycled wool product. Other fabrics are available for acoustic or decorative purposes.

The standard operating speed is around 140mm/s which enables a 5m tall banner to deploy in 35s.

Designed and Manufactured in the UK.

Features

• Tubular Motor (typically Becker)

• End of Travel & Ultimate Limit Switches

• Standard power requirement of 230v 13A power supply per banner location.

Control Option One

• Uses the JCJ Conductor Control System, enables advanced control over a number of options using a tablet interface.

• Requires a 300x300 enclosure for electronics. Can be mounted on the unit (shown below) or the wall.

• Allows preset positions, individual and group control of up to 100 banners, with movement based on meterage or percentage of travel.

• Absolute Encoder (optional extra, shown below)

• Secondary Brake (optional extra, shown below)

• E-Stops compliant with ISO 13850 & can interface with other stage engineering packages through a global e-stop system.

• Can integrate into a building management system.

Installation

• Mounting brackets provide a simple wall or ceiling fix. The same part is used for both scenarios. Once the brackets are fixed, the banner slots into place and is fixed with a bolt.

• J&C Joel can provide full installation services or supply mechanical and electrical drawings to aid your installation.

Control Option Two

• Uses the motor manufacturer’s propriety software, allows control of upto 100 units from a mobile device

• Can be integrated into a building management system (BMS).

• Control via radio frequency, with the motors providing positional feedback to the control and signal amplification

• Application allows multiple pre-set positions for banners based on percentage of deployment.

Showcase

Sevenoaks School, UK - Double Roller Banners

Concertina Banner

Concerto

The preferred option when large-scale acoustic absorption performance is required. The absorption is achieved by two layers of Tay Wool Serge, held together at regular intervals by horizontal slats. This achieves a Class A acoustic absorption rating according to EN ISO 11654:1997. These keep the air gap between the layers constant and help the fabric stack neatly as it is raised.

The Concerto offers up to 50m2 of absorbent material, with a maximum width of 6m or a maximum drop of 20m. Standard operating speed is 100-150mm/s which enables a 6m banner to deploy in 60s. Designed and Manufactured in the UK.

Features

• NORD IE3 3 Phase Braked Geared Motor

• Localised NORD Inverter Drive

• Mayr ROBA Stop Stage Safety Brake

• TER Limit Switch - End of Travel & Ultimate

• Absolute Rotary Encoder

• Overheat prevention

• Requires a single phase 13 amp 230V power supply per banner.

• E-Stops compliant with ISO 13850

• Tay Wool Serge is our standard fabric which has tested acoustic reports. Other fabric options and colours are also available upon request for varying aesthetic and acoustic performance.

Installation

• Two Unistrut P1000 channels along the full length of the top of the banner enable simple mounting.

• J&C Joel can install the banners or can provide mechanical and electrical drawings to aid your installation.

Report Number C/23171/T01

Tests have been done in SRL's Laboratory at Holbrook House, Sudbury, Suffolk, to determine the sound reduction index of various drapes in accordance with BS EN ISO 10140-2:2010

From these measurements the required results have been derived and are presented in both tabular and graphic form in Data Sheets 1 to 9.

The results are given in 1/3rd octave bands over the frequency range 50Hz to 10kHz, which is beyond that required by the test standard. Measurements outside the standard frequency range are not UKAS accredited.

Appendix A -Test Method

Measurement of Sound Transmission in accordance with

BS EN ISO 10140-2: 2010 – TP33

In the laboratory, airborne sound transmission is determined from the difference in sound pressure levels measured across a test sample installed between two reverberant rooms. The difference in measured sound pressure levels is corrected for the amount of absorption in the receiving room. The test is done under conditions which restrict the transmission of sound by paths other than directly through the sample. The source sound field is randomly incident on the sample.

The test sample is located and sealed in an aperture within the brick dividing wall between the two rectangular reverberant or acoustically "live" rooms, both of which are constructed from 215mm brick with reinforced concrete floors and roofs. The brick wall has dimensions of 3.9m wide x 2.9m high and forms the whole of the common area between the two rooms.

One of the rooms termed the source room has a volume of 55 cubic metres and is isolated by the use of resilient mountings and seals, from the surrounding structure and the adjoining room. The adjoining receiving room has a volume of 50 cubic metres.

Broad band noise is produced in the source room from an electronic generator, power amplifier and loudspeaker. The resulting sound pressure levels in both rooms are sampled, filtered into one third octave band widths, integrated and averaged by means of a Real Time Analyser using a microphone on an oscillating microphone boom. The value obtained at any particular frequency is known as the equivalent sound pressure level for either source or receiving rooms. The change in level across the test sample is termed the equivalent sound pressure level difference, i.e.

D = L1 - L2

where

D is the equivalent sound pressure level difference in dB

L1 is the equivalent sound pressure level in the source room in dB

L2 is the equivalent sound pressure level in the receiving room in dB

172 Page 22 of 25 Date: 12/11/2015 This report shall not be reproduced, except in full, without written approval of SRL Technical Services Limited

The Sound Reduction Index (R), also known by the American terminology Sound Transmission Loss, is defined as the number of decibels by which sound energy randomly incident on the test sample is reduced in transmitting through it and is given by the formula:

R = D + 10log10 S A ………..in decibels

Where

S is the area of the sample (m2)

A is the total absorption in the receiving room (m2)

both dimensions being in consistent units

The Sound Reduction Index is an expression of the laboratory sound transmission performance of a particular element or construction. It is a function of the mass, thickness, sealing, method of mounting etc., and is independent of the overall area of the sample.

However, when a sample is installed on site and forms part of an enclosure of building, the sound insulation obtained will be dependent upon its surface area, th e larger the area the greater the sound energy transmitted, as well as the absorption in the receiving area. In addition, the overall sound insulation of an enclosure is also determined by the sound transmission through other building elements, some of which may have an inferior performance to the sample. Because of this the potential Sound Reduction Index of a sample is not always fully realised in practice. A further consequence is that the Sound Reduction Index of a particular sample can only successfully be measured in a laboratory because only under such controlled conditions can the sound transmission path be limited to the sample under test.

Rw, C and Ctr have been calculated in accordance with the relevant section of BS EN ISO 717-1:1997 from the results of laboratory tests carried out in accordance with BS EN ISO 10140-2:2010.

Identification:

Basic Acoustics

Sound is made up of vibrations or sound waves, formed by objects shaking back and forth. These sound waves travel through air, water and solid objects. When they reach our ears, they make the delicate skin of the eardrums vibrate and translate into sounds we recognise.

The scientific study of sound waves is known as acoustics.

The following pages are designed to act as a guide to help you understand some of the key factors involved in acoustics. Our aim is to get you thinking about your space, the type of performance(s) you are wanting to stage and the problems you are seeking to overcome.

We would always advise you to seek input from a professional acoustician. Our expert team is always on hand to facilitate such a conversation, offering guidance and support as to which products are most suitable to meet your needs.

Decibels (dB)

The decibel (dB) is the unit used to measure the intensity of a sound. Your ears can hear everything from your fingertip brushing lightly over your skin to a loud jet engine.

The higher the decibel level, the louder the noise. On the decibel scale, the level increase of 10 means that a sound is actually 10 times more intense, or powerful

Frequency is the speed of the vibration and determines the pitch of the sound. Frequency is measured as the number of wave cycles that occur in one second, this unit is measured in Hertz (Hz). Humans can detect sound in a range of 20Hz to 20kHz.

Sound waves interact with objects in a room differently and can cause acoustic issues. Low frequencies are more difficult to control, due to short reverberation times and often full acoustic solutions are required to deal with these. Mid or high frequencies have a longer line of reverberation, so it’s important to understand the sound you are dealing with.

Reverberation Time

Sound in a room will repeatedly bounce off surfaces such as the walls, the ceiling and floor or other hard surfaces. When these reflections combine, a phenomenon known as reverberation is created. Reverberation reduces when the reflections hit absorptive surfaces such as curtains, soft furniture and even people.

The reverberation time of a room or space is defined as the time it takes for sound to reduce (or decay) by 60dB. For example, if the sound in a room took 5 seconds to decay from 90dB to 30dB, the reverberation time would be 5 seconds.

In order to enhance the experience for your audience, it is vital to understand the acoustic requirements of the performance as these need to be in harmony with the reverberation time of the space.
