The SPLM is a digital sound pressure level meter used to measure SPL in decibels, from 30 to 130dB. It is portable, easy to use, and ideal for measuring and monitoring noise and sound in any environment. The unit can be used for independent on-site readings or set to monitor and measure dB variances in an area over a period of time. When connected to a PC or laptop and using SoundLAB software (downloadable for free), you can analyze the recorded measurements.
