Beschreibung
SPL Lab presents the USB Noise Meter (Pro Edition), an innovative measurement microphone that is unique due to its technical data. It is equipped with a frequency range of 10 to 20,000 Hz, which enables an amplitude range of 80 to 150 dB and a wide dynamic range of 70 dB. The integrated ADC 16-bit unit and the mini USB socket make the device very user-friendly. In addition, free software is available that enables extensive spectral analysis, measurement of the absolute sound pressure level and adjustment and alignment of the AFC. Slim and compact, with an anodized aluminum housing, these are the features of this high-quality measurement microphone.

ergonomics
The USB noise meter is made of anodized aluminum, which contains the high-sensitivity microphone insert, the low-frequency amplifier and the ADC unit with USB connection for data transfer. There are special notches in the body of the device around the microphone insert to obtain smoother directivity. The device is acoustically correctly designed in the housing to avoid additional overtones and distortion. If necessary, the noise meter can be installed on the stand.
