The Triplett SLDL20 USB Sound Level Datalogger can be used to test and verify sound levels for worker safety (OSHA), community noise ordinances, night clubs/concerts, airports, mines, athletic events, construction sites, vehicle testing, wind farms, new product noise reduction, and other applications. The Sound Level Meter meets IEC 61672-1 Class 2 with ±1.4dB accuracy. It can datalog up to 129,920 readings with user programmable sampling rate (1 second to 24 hours) and date/time stamp. It features a 30 to 130dB range plus A and C weighting with selectable fast/slow response time. Additional features include: user programmable high/low alarms, 2 LEDs that display operation, alarm, battery, and memory status, Min/Max, and automatic or manual start. Includes wind screen, (1) lithium battery (Triplett 37-66), and software. 1 year warranty.

Q. Do Triplett sound level meters measure impact noise or low-frequency noise?
A. 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.
Q: I've noticed most ear plugs, including ones I'm considering, are rated at dB32. What is a typical and safe dB level for the human ear? When would I need to use earplugs with a dB32 rating?
A: 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).
