toolBox for acoustics

By acoustassist

This app is only available on the App Store for iOS devices.


toolBox for acoustics is a suite of information, equations and calculators for all things acoustics-related, useful for consultants, engineers, researchers and students alike with an interest in sound, noise and vibration.

toolBox is, and always will be FREE with no ads!

Useful features include:
- Selection of audio test signals, with the option to download signals for offline use
- Unique decibel calculator
- Room modes calculator
- Octave/third-octave frequency bands calculator with A/B/C/D weightings
- Noise rating (NR) level calculator
- Reverberation time calculators (simple and advanced modes)

In addition, a number of acoustic equations are included, each with the unique provision to calculate any one of the equation terms. Physical units are always selectable where appropriate, for example speed may be calculated or input as m/s, km/h or mph. Equations cover:
- Speed of sound
- Decibel definitions of sound power, intensity and pressure level
- Audio delay
- Sound propagation
- Distance attenuation
- Barrier attenuation

Also provided is background information to some key acoustic concepts and a directory of acoustic related organisations.

Please note: some current facilities follow the convention for the UK acoustics industry, which might differ in other countries. For example, in the UK the decibel reference value for sound pressure in air is 0.00002 Pa.

toolBox for acoustics will be updated over time with more great features. For any feedback (positive or negative!), please contact us via our website.

Customer Reviews

Everything you need, but...

So this app has everything you need to get accurate measurements however; this needs an update! While using the advanced reverberation calculator, I could have entered half of the required values before it crashes.

When I try to enter specific values and attempt to export it, so I can re import the values in the event of a crash, the app cuts half of the page preventing me from copying the generated data. When I try to go to the home page and reload the calculator, the app will crash again.

Please look into resolving this issue as soon as possible. My device is currently running iOS 9.3.1
