Decibel Meter: Sound Analyzer

Measure, record and track sound levels in your environment with Decibel Meter Ultra, the all-in-one sound level meter, dosimeter and real-time analyzer.

From monitoring sound levels in the workplace, noise levels at home, 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.

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.

Eliminate Nuisance Noise:
Getting proof is as simple as tapping a button. Catch and log problem noise as it occurs. Create comprehensive acoustic analysis reports that you can share easily via PDF. Visualize sound levels over time and gather the evidence that you need to take decisive action.

Elevate Your Home Audio:
Get the best from your home audio system with powerful fractional octave band analysis. Fine-tune your equipment using up to twelfth octave-band resolution, variable time weightings and peak level indicators so that you can enjoy music and movies like never before.
