Sound has always been an inseparable part of our lives, and sometimes noise may be irritating and cause a nuisance to our daily operations. It is easy to know that there is noise around us, but it is difficult to know where the noise comes from and how loud the noise is. Acoustic Instruments can be a solution to this. With Acoustic Instruments, we can make sound visible, identify the source, and control noise to an acceptable level.
Acoustic beamforming arrays, commonly known as acoustic cameras, enable the user to visualise different sound sources at different frequencies and source strengths. The resolution and ability to resolve sound sources spaced closely apart, and at lower frequencies, is mainly decided by overall size and number of microphones of the equipment being used. Although image manipulation and deconvolution techniques on the beamformed results might give added resolution, in practise the properties of the array still influence the results. This size versus resolution criteria is the crux of the acoustic camera market.
The Acoustic Camera gives the user both portability and great resolution for a wide range of measurement situations. The array dish is based on a hexagon shape, given it both its name, and the ability to combine several tiles into larger systems.

Sound Level Meter
The latest single or dual channel sound analyser covers a large variety of applications including building acoustics, sound intensity, environmental noise assessments, noise at workplace, product noise testing and more. The Sound Level Meter is a smartphone friendly device. Simply connect your smartphone or tablet with application installed, you can take full control of the instrument by integrating photos and voice notes obtained on your smartphone or tablet with markers to your noise data.
