Acoustic Imaging

Acoustic Imaging is probably the most advanced field within the whole of acoustics and finding the right products can be a bit of a minefield. At AcSoft we have the expertise to make sure you have the very best product for your application.

An acoustic camera is an imaging device that is used to both locate sound sources and to characterise them. It generally consists of a microphone array and an optical camera whose data is simultaneously acquired to give a representation of the location of the sound sources. The most popular method to obtain an acoustic image is to use beamforming whereby microphone signals are delayed relatively and added, with the signal coming from a specific direction being amplified while signals coming from other directions are cancelled.

Alternatively, particle velocity techniques can be used for localising sound sources on any type of object; from small hearing aids to large gas turbines. This technique provides you with high spatial resolution sound maps, over a broad frequency range and with an incredible dynamic range.

Aerospace

All industry applications bring their own challenges, but aerospace testing can be one of the harshest, pushing transducers and measurement systems to their limits. At AcSoft we know that measurements often need to be carried out in high speed, turbulent air-flows, where it is vital that the measurement technique itself does not affect the measurements - and where the testing equipment has to be durable under extreme conditions. Often you only have one chance to record data so validation is vital.

And because we work closely with you, we are well aware of your needs and the challenges you face in such a unique industry. If we can improve your testing, you can improve your products.

Building Acoustics

Building Acoustics (also known as architectural or room acoustics) is the science and engineering of achieving a good sound within a building. Building acoustics is generally about achieving good speech intelligibility in a theatre, restaurant or railway station, enhancing the quality of music in a concert hall or recording studio, or suppressing noise to make offices and homes more productive and pleasant places to work and live in.

A key parameter in building acoustics is reverberation time which is a measurement of the way a space ‘sounds’ and hence gives an indication of the intelligibility of sound in that space. A high reverberation time, for example, can make a room sound muffled, loud and noisy. Rooms designed for speech typically have a low reverberation time whereas a higher reverberation time can add depth, richness and warmth to music.

The reverberation time of a room is defined as the time it takes for sound to decay by 60 dB after an abrupt termination.

Calibration

Its now been a year since AcSoft setup its own noise and vibration calibration laboratory and our offering has grown from strength to strength.

Our lab is run by Alex Santana who qualified in acoustics in his home city of Las Palmas de Gran Canaria (although we don't know why anyone would want to leave the sunshine of Gran Canaria!). Before joining AcSoft he worked in the UK for a number of years in the pro-audio world of loud speaker design.

Our first task as a laboratory was to directly replicate the microphone calibration system used by "GRAS Sound & Vibration" in Denmark, parent company of our very own GRAS UK. This allows us to fully calibrate 1/8, 1/4, 1/2 and 1 inch microphones both from GRAS or any other manufacturer and all traceable to national standards.

We then replicated the complete Svantek acoustics calibration system so we can calibrate all Svantek instruments and calibrators. With this system we can perform a full factory calibration on all Svantek instruments which means all new instruments we ship to customers have a fresh calibration certificate every time. In addition to Svantek instruments we can calibrate those made by other companies as long as we can get hold of the relevant technical data. Our library of data is growing rapidly so why not ask if we can calibrate your instrument.

The last part of our capability to go in was a vibration calibration fixture. We use a Data Physics 16kg shaker together with Soundcheck software (from Listen in the States) and a Dytran reference accelerometer to give us a wide range of capabilities.

All our kit is housed in an air conditioned, purpose built laboratory and is calibrated to nationally traceable standards. Next on our agenda is to go for ISO17025 and UKAS accreditation but that normally takes a year to achieve so watch this space!

Electroacoustic Testing

Electroacoustic transducers find their way into all corners of our lives, including telephones, loudspeakers, hearing aids, car stereos, music players, military headsets, microphones, and the list goes on. In these days of high volume production and quality control, a test system is needed to provide the answers quickly and accurately.

New devices are launched almost daily that push the boundaries of design. The latest smartphone must squeeze in ever-more impressive capabilities to compete in a crowded market while complying with international telephone standards for voice capture and reproduction. Whether customers want open-backed headphones or flat frequency response speakers, manufacturers need to deliver the sound quality that buyers expect from their favourite brand.

To deliver quality sound, it is essential to analyse the sound produced and captured during R & D. Many parameters are critical to authentic sound reproduction including distortion, frequency response, and directivity. Finding the right balance normally requires many tests so automation, data correlation, and ease of use help ensure productive electroacoustic testing.

Environmental Noise & Vibration

Noise and vibration in the environment affects us all, whether it's your next door neighbour’s dog barking, that annoying whine from a distant power station or the ground borne vibration from a pneumatic breaker outside your office. Measuring environmental noise and vibration in a meaningful way can be difficult, and many descriptors have emerged to try to quantify annoyance by using temporal or frequency analysis.

Environmental noise is the combination of noise pollution from outside, caused by transport, industrial and recreational activities. The effects on us of being exposed to environmental noise can vary from emotional to physiological and psychological. Noise at low levels is not necessarily harmful and environmental noise can convey a sense of liveliness in an area, however, the negative effects of noise exposure can include interference with speech, annoyance, sleep disturbance, anxiety, hearing damage and stress-related cardiovascular health problems. Environmental noise is studied, regulated and monitored by many governments and institutions, as well as forming the basis for a number of different occupations.
