When people first use a dosimeter, they tend to be surprised at its sound pressure level, which is much higher than they expect. The sound pressure level is set by the manufacturer and corresponds to the sound pressure level and the scale of the monitor. Sound-pressure level is commonly measured in decibels (dB), but it is expressed on a logarithmic scale. The sound-pressure level in dB is simply the square root of the ratio of the square of the sound pressure (P) to the pressure of one millibar (1 millibar = 10-3 of atmospheric pressure).
Those individuals with hearing loss are more sensitive to the effects of noise. Noise dosimeters, which are similar to SLMs, measure the impact of noise on the user. They provide protection through various alert mechanisms based on a noise level setting. The dosimeters are available in two basic types, Type 1 and Type 2. Both can be configured to measure sound pressure level in decibels. When connected to a computer, they can be set to periodically measure the instantaneous sound level, which can then be used to build an audiogram. The user can then set the dosimeter’s alert to warn when the sound pressure exceeds the user’s set level.
As a practical matter, sound pressure levels and sound fields are measured in decibels and sound power levels in decibels squared (dB2). The decibel and dB2 scales are linear, so dB and dB2 are mathematically identical. Sound power (W) is the product of sound pressure (p) and sound speed (c).
