Specialist Groups

The Institute reflects the broad spectrum of the science and application of acoustics and several Groups have been formed to foster contacts between members of the various specialist areas.

Building Acoustics

The Electro-Acoustics Group of the IOA is the home for specialists in all aspects of sound equipment and sound systems design. 
The group holds an annual conference, called Reproduced Sound, usually in late November. This event, which celebrated its 25th anniversary in Brighton in 2009, attracts delegates from all over the world. 

Reproduced Sound meetings cover topics such as loudspeaker and microphone design, multi-channel audio, speech intelligibility and leaks into the Noise at Work Act as it pertains to the entertainments industry. 

The group is also discussing ways to improve the outcomes of the use and installation of equipment, by trying to get involved in training initiatives in the industry. A critical concept we are exploring is "training the teachers", a way that expertise can be transferred to those in the front line of education, to help them with resources to improve their delivery, and thus the quality of graduates coming into industry. 

Environmental Noise

Chair: Mr Steve Mitchell MIOA

Contact us

The Environmental Noise Group comprises members of the Institute of Acoustics with a particular interest in assessment and control of environmental noise and vibration. The aim of the group is to provide a forum for members to exchange information and discuss developments within this general field of interest including noise and vibration control, prediction methods and the effect on receptors (not just people). 

The ENG committee is elected, but is controlled to ensure a broad range of representation, including Environmental Health Practitioners, Consultants, Education and Governmental Organisations. It organises events of interest to the membership, issues regular communications and represent members’ interests within the IOA and on relevant external bodies. It also briefs Council on related consultation documents.

Measurement and Instrumentation

Chair: Mr John Shelton MIOA

Musical Acoustics

Chair: Mr Mike Wright MIOA

Secretary: Mr David Sharp MIOA

Contact us

The MAG has a very important part to play in the understanding and research of many aspects of acoustics. The obvious connections between music and acoustics include the design of opera, concert and recital performance venues, studio and practice room acoustics and design. 
However, aspects such as musical instrument design, music technology, music therapy, musical perception, the singing voice, the use of electronics in musical performance and reproduction also encompass a wide field of acoustical knowledge. 
The mission of the MAG is as follows:
• To encourage closer working with professionals in related disciplines such as architects, musical instrument designers and builders, sound engineers, performing musicians and composers, musical education, music in health and wellbeing.
• To be a forum for members and other professionals with an interest in all aspects of musical acoustics.
• To promote a wider understanding of musical acoustics to academics, professionals in all related fields and increase public awareness.
• To hold regular meetings (with access available to related professional disciplines) for the interchange of information and experiences.

Noise and Vibration Engineering

Chair: Dr Malcolm Smith MIOA

Noise and Vibration Engineering Group: members, committee and mission

Members

The NVEG is a special interest group within the IoA comprising members with some combination of the following interests:

- Engineering noise control
- Vibration control
- Assessment of workplace noise and vibration
- NVH assessment
- Low noise design
- Noise source mechanisms
- Measurement methods for source identification
- Noise and vibration prediction methods

Members are likely to have other related interests, such as the physical effect of noise on humans, measurement methods and standards, noise or vibration induced fatigue, underwater acoustics, etc. The activities of NVEG should reflect the fact that these interests may also be represented by other IoA Groups, and that joint meetings may be appropriate.

The members of NVEG will generally have to work closely with people outside the field of acoustics (safety officers, designers, architects, etc.) and are thus likely to be interested in events organised jointly with other appropriate organisations.

Committee

The purpose of the committee is to:
- organise events of interest to NVEG members
- represent members interests within the IoA
- represent the IoA on external bodies with respect to noise and vibration engineering issues.
- keep members informed via a newsletter or other communications

Mission

The Noise and Vibration Engineering Group comprises members of the Institute of Acoustics with a particular interest in assessment and control of noise and vibration. The aim of the group is to provide a forum for members to exchange information and discuss developments within this general field of interest, including engineering methods for noise and vibration control, workplace noise or NVH assessment, low noise design, source identification methods, source mechanisms and prediction methods. The NVEG committee organises events of interest to the membership, issues regular communications and represent members’ interests within the IoA and on relevant external bodies.

Physical Acoustics

Chair: Acting: Mike Swanwick FIOA

Contact us

Physical acoustics is the fundamental science that underpins the acoustics we work with every day. The way sound propagates, scatters, attenuates, how it interacts with structures and measurement equipment should concern us all. Having a basic knowledge of physical acoustics enables us to make better decisions, design better products, make better measurements and write more accurate reports. The study of physical acoustics is also developing new ways of interpreting acoustical data including medical ultrasound and imaging, the use of advanced materials for sound absorbers and noise barriers, and many more applications for now and in the future.

The aim of the Physical Acoustics Group is to provide:

Specialists and novices alike from academic or industrial backgrounds a forum to discuss, disseminate, and develop physical acoustics at all stages of development from theory to the provision of exploitable technology in industry.

IOA members who have a particular interest in physical acoustics with a programme of events that captures the essence of latest research and the state of the art understanding of; fundamental acoustic interactions from sound sources, via various media (solid, liquid or gas) to receptors.

Representation of the IOA at Institute of Physics (IOP) PAG events, and vice versa. The IOP also have a PAG, so we coexist with a common cause to further the field by supporting events from each institute.

In addition, the group acts as a point of contact for individuals and organisations from all backgrounds that share a common interest, and welcomes their suggestions for topics and their involvement in providing presentations and organising events.

Senior Members Group

Chair: Mr Ralph Weston MIOA

Secretary: Mr Mike Forrest MIOA

Contact us

The SMG was created at the behest of the Vice-President Groups and Branches 6 years ago when it was felt by the IOA that retired members, and those approaching retirement, were being neglected and were a resource of experience that should be utilised by the IOA.

It is an opportunity for older members to get together from time to time formally and semi formally to discuss issues arising from the IOA and to listen to speakers covering all aspects of acoustic science. At the same time there is an opportunity for members to meet sociably and to network.

One of the objects of the group is to communicate with those members of the IOA who have retired and are living overseas.

It is recognised that Senior Members live all over the country and that travel is not only expensive but can present challenges to attend meetings. Consequently all communications between the committee and Senior Members is by email.

One or two half day meetings are held each year when we meet for a buffet lunch followed by a short business meeting if necessary and then a talk. Timings are planned to miss rush hour travel and to enable train travel to attract discounts. Meetings usually close by 15:30 hrs.

Senior members assist with the CPD programme and are available to assist with the YMG.

Speech and Hearing

Chair: Dr Gordon Hunter MIOA

Secretary: Derek Nash MIOA

Contact us

The Speech and Hearing Group provides a forum for IOA members with an interest in acoustic aspects of speech and hearing. These include speech intelligibility, perception and production, hearing protection, audiology, assistive and other technologies for speech and hearing, and speech and language therapy.

The Speech and Hearing Group committee is active in organising meetings aimed at raising awareness of the subject and advancing technical development through the sharing of knowledge and experience. The group acts as a point of contact for individuals and organisations from all backgrounds that share the common interest, and welcomes their involvement.

Underwater Acoustics

Chair: Dr Peter Dobbins FIOA

Contact us

The aim of the Underwater Acoustics Group (UAG) is to attract the interest and commitment of all professionals from industry, academia and government who work in underwater acoustics in order to help advance our understanding of this field. 

The group covers a wide range of topics including natural and anthropogenic sound and its generation underwater; sonar transducers; sonar signal processing; sonar performance predictions; multi-beam and bathymetry sonar systems; underwater communication; the propagation, reflection and scattering of sound in the underwater environment including the seabed and the sea surface; and bioacoustics. 

The UAG Committee represents the members of the IOA who have an interest in underwater acoustics and generally supports the subject within the UK. The Committee’s three main roles are:

• Work with professionals to arrange conferences for the underwater acoustics community. 
• Provide feedback to international standards committees.
• Recommend the recipient of the A B Wood Medal. 

The A B Wood medal and attendant prize is aimed at innovative underwater acousticians under the age of 40 for distinguished contributions to the application of underwater acoustics. The award is made annually, in even numbered years to a person from Europe and in odd numbered years to a person from the USA/Canada. Nomination forms and details can be found here

Young Members

Chair: Mrs Angela Lamacraft MIOA

Contact us

The IOA's active Young Members' Group aims to bring together a diverse network of acoustics professionals in the early stages of their career - by promoting peer knowledge sharing and peer support and providing a link to the knowledge of established acousticians and a platform for the continuing development of new and existing skills.
As well as being a good introduction to the IOA, the Young Members' Group organises a variety of activities, such as presentations and architectural tours, and encourages input from members as to how best it can meet their needs. 
We look forward to welcoming you to our group and helping wherever we can!
