About Decibel Meter Ultra

From monitoring sound levels at home, noise levels in the workplace, to calibrating the speakers of your hi-fi, Decibel Meter Ultra makes it easy to get the information that you need. Precision Metering For Sound: Get accurate sound level readings using industry standard measurement methodologies, selectable A, C and Z frequency weighting curves, fast and slow time-weightings, plus concurrent peak level measurement. Choose from the built-in microphones on your device or connect an external microphone* for an even broader dynamic range. Eliminate Nuisance Noise: Getting proof is as simple as tapping a button. Catch and log problem noise as it occurs. Overlay live video with sound levels, or create comprehensive acoustic analysis reports that you can share easily via PDF.

Safeguard Your Hearing: Stay aware of noise levels in the workplace and compare against industry-mandated safe levels using the built-in dosimeter. Select from default measurement profiles based on published recommendations from NIOSH and OSHA, or if you’re working against a different specification, create your own.
