Description

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 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. Visualize sound levels over time and gather the evidence that you need to take decisive action.

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.

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.

Download now and take advantage of our free plan which includes our built-in metering profile and up to two-minute recording durations. Or choose one of our PRO plans and gain access to everything the app has to offer, including our full suite of professional metering options, custom meter profiles, analysis charts, PDF reports, background recording, unlimited recording durations and more.

*External microphones require calibration against a reference sound level source

‘Perfect on the Road Meter

Works like a charm. I travel up and down the country setting up for music gigs and there’s no difference in readings between this and my dedicated meter! Don’t think I’ll even bother putting it in my bag anymore. Amazing!
