The technical program included plenary lectures, invited lectures and papers as well as poster presentations on all aspects of acoustics. Special sessions were dedicated to young acousticians, acoustics in industry and public relations.

In 2025, MTG will continue to focus on sound sensor technology, e.g. measuring capsules, amplifiers, measuring microphones, sound intensity probes, outdoor and environmental microphones, calibrators, power supplies and turnkey system solutions, such as complete test benches for indoor and outdoor use.

Further developed digital microphone solutions, such as the MV 240 USB with an extended range of functions, were also presented for the first time.

Product innovation: MV 240 USB

With the MV 240 USB, Microtech Gefell is launching a measurement microphone amplifier in a class of its own!

The MV 240 USB is a measurement microphone amplifier with an integrated 2x 32-bit gain-range AD converter for externally polarized or pre-polarized measurement capsules. The digital 32-bit output signal with up to 192 kHz sampling frequency corresponds to calibrated sound pressure values and reproduces more than the entire dynamic range of a measurement capsule. The MV 240 USB is automatically recognized under Windows, MacOS, iOS, Android and Linux and is powered directly via the USB interface.

Thanks to its versatility and the impulses from the field, the application possibilities of the MV 240 have been greatly expanded.

It differs fundamentally in design and quality from all standard analog-digital solutions on the market and is constantly being developed further.

Current development topics include, for example, synchronization via the time stamp of a GPS sensor, e.g. for drive-by solutions or the expansion of the range of applications by combining it with mobile devices.

The MV 240 digital thus opens up a multitude of new applications that could not be realized with previous analogue or conventional analogue-digital solutions for cost or functional reasons.
