PTB’s high-frequency personal sound exposure meter in use

At many workplaces, the prevailing sound exposure is caused by sound in the high-frequency audible range or even by ultrasound. It has to be possible to detect noise exposure with a small measurement uncertainty even in this frequency range. PTB’s concept of a mobile high-frequency personal sound exposure meter is suited to measuring a large number of quantities that are typical of the audible range and can now also be measured in the ultrasound range as noise an individual person is exposed to. This novel concept thus contributes to improved occupational safety. (Technology Offer 7095)
