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).
Triplett SLM400-KIT Sound Level Meter (SLM) with Calibrator Kit is a comprehensive package that includes a sound level meter instrument along with a calibrator. The calibrator is a reference tool used to verify and adjust the accuracy of the sound level meter, ensuring reliable and accurate sound measurements.
Calibration is essential to ensure that the sound level meter provides accurate and consistent measurements. Over time, factors such as wear, temperature, and humidity can affect the instrument's accuracy. Regular calibration with a calibrator helps maintain measurement reliability.
A typical calibrator kit includes Type 2 Sound Level Meter with 9V battery, windscreen, plus Sound Level Calibrator with mini screwdriver and 9V battery, stored in a hard carrying case.

Software

I think we can all agree that the loss of one of our most important senses – “hearing”, is something we all want to prevent for as long as we can! A sound level meter is a device used to measure the intensity of sound waves. Being aware of the intensity of sound exposures helps you determine what precautions should to be taken to protect human ears from any noise that rises above the “safe” threshold.

A sound level calibrator is a tool that outputs “known” reference dB levels – typically (2) levels of 94 and 114dB @ a 1 kHz frequency. This allows for simple end user calibration of a sound level to ensure it’s at its best accuracy before each use.

With the SLM400-KIT you get both of these pieces together in a kit to monitor sound levels and ensure they are safe! These are widely 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 type 2, ANSI S1.4 Type 2 with ±1.5dB accuracy. It features a 35 to 130dB range plus A and C weighting with selectable fast/ slow response time. Includes 9V battery and windscreen, and hard carrying case. The kit is also available with a NIST Traceable Certificate option when ordering.
