In the listening business for almost 20 years
Richter has been in the listening business for almost 20 years and is therefore a professional in the detection of sound sources. “You are sensitized and hear differently than other people,” he says. But his trained ears and the conventional sound level meter still reach their limits in very difficult conditions. Then the acoustic camera comes into play because it detects the loudest machine even in a narrow, noisy room. “This was the case, for example, when it was necessary to find the loudest machines in a production hall with packaging machines in order to protect employees from noise,” says Richter.
For example, the camera can show the noise-intensive areas of an engine, a combined heat and power unit or a wind turbine. It is also very helpful when searching for acoustic leaks. For example, it has already been necessary to analyse and illustrate the inadequate soundproofing of a partition wall between two hotel rooms. This revealed that sockets had apparently been misplaced and that the mineral wool in the lightweight wall under investigation had not been installed over its entire surface. If recourse claims are to be asserted, a picture-acoustic representation can be very convincing.
As an accredited measurement centre for noise and acoustics in accordance with §§ 26, 29b BImSchG (Federal Noise Protection Law), DEKRA supports: noise emission measurements and forecasts, building and room acoustics, noise at the workplace as well as vibrations and oscillations.
