AC100 Acousticam

Quickly and effectively locate and analyse sound sources

The AC100 AcoustiCam from Sinus is a portable and easy to use acoustic camera. It is ideal when you need to quickly identify and find the precise location of closely located sound sources. It has a multi-microphone array that uses beamforming techniques to overlay an acoustic image onto a visual image that allows you to simply see your sound sources. It is especially good for the sound analysis of complex objects and often reveals issues where conventional measurements techniques using a single or just a couple of microphones have difficulty.

Due to its state-of-the-art microphones in MEMS technology with integrated AD converters and 51.2 kHz sampling rate, together with an integrated measurement data processing electronics in the latest DSP technology, the AC100 is now affordable for a wide range of users. The complete integration in the array, with only one USB interface for data and power supply, allows for convenient mobile use with any Windows PC.

The AC100 is a compact and very easy-to-use acoustic camera for standalone applications. Because of its high performance, simple operation and fair price, the AC100 is suitable for a wide range of applications in research and production.

The AC100 is supplied either as pure hardware + Windows driver for custom development or bundled with the BeamformX application software from OptiNav.

Typical Applications Include:

Localisation and separation of sound sources to reduce the noise emitted by vehicles, machinery, household appliances and electric tools
Source analysis for acoustic design of wind tunnel models, complex vibrating structures, creaking or rattling structures
Long-term monitoring of machines and plant
Acoustic vehicle tests (inside and outside)
Quality assurance
Predictive machine maintenance
Acoustic optimisation of product
