Web25 de jan. de 2024 · When you measure noise levels with a sound level meter, you measure the intensity of noise called decibel units (dB). A sound meter uses a display with a decibel range and resolution to approximate the ear’s dynamic range, usually the upper range rather than the quiet part. If you think about it, it would be very difficult to manufacture a ... WebIn audiology measurements, the reference level for the decibel shown on audiograms is the biologic normal hearing baseline, or 0 dB HL. Because of the loga-rithmic nature of the decibel scale, every 10-dB increase represents a 10-fold multi-plication of sound.
