User Manual (PDF)
Triplett sound level meters are not specifically designed for measuring impact or low-frequency noise. They are intended for general-purpose sound level measurements within the typical human hearing range, covering approximately 30 to 130 decibels and frequencies from 30 Hz to 8 kHz. For applications requiring detection of impact or very low-frequency noise, a specialized meter may be required.
Noise levels above 70 dB over extended periods can start to damage hearing. Extremely loud noises, surpassing 120 dB, can cause immediate damage. The dB32 rating of earplugs indicates the amount of noise reduction they provide. For specific applications of your earplugs or hearing protection, it's best to consult with the manufacturer directly. It's worth noting that OSHA mandates employers to initiate a hearing conservation program when noise exposure reaches or exceeds 85 decibels averaged over an 8-hour workday, known as the 8-hour time-weighted average (TWA).
