What is PEAK LEVEL?
PEAK LEVEL is the absolute highest pressure wave that is detected by the microphone. Unlike the MAX LEVEL, PEAK is detected independent of dosimeter settings for RESPONSE or WEIGHTING. The PEAK circuitry responds in 50 micro seconds usually with Linear Weighting (depends on dosimeter model). Test this by simply blowing across the microphone. You will notice that the peak reading may be 120dB or greater. When taking a long term noise sample (such as a typical 8 hour workday sample for OSHA compliance), the peak level is often very high.
