toolBox for acoustics1.1.0

★ 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. ★

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.
