★ toolBox for acoustics is a suiteofinformation, equations and calculators for allthingsacoustics-related, useful for consultants, engineers,researchersand students alike with an interest in sound, noise andvibration.★Useful features include:⁃ Selection of audio test signals, with the option todownloadsignals for offline use⁃ Unique decibel calculator⁃ Room modes calculator⁃ Octave/third-octave frequency bands calculator withA/B/C/Dweightings⁃ Noise rating (NR) level calculator⁃ Reverberation time calculators (simple and advanced modes)In addition, a number of acoustic equations are included,eachwith the unique provision to calculate any one of theequationterms. Physical units are always selectable whereappropriate, forexample speed may be calculated or input as m/s,km/h or mph.Equations cover:- Speed of sound- Decibel definitions of sound power, intensity andpressurelevel- Audio delay- Sound propagation- Distance attenuation- Barrier attenuationAlso provided is background information to some keyacousticconcepts and a directory of acoustic relatedorganisations.Please note: some current facilities follow the conventionforthe UK acoustics industry, which might differ in othercountries.For example, in the UK the decibel reference value forsoundpressure in air is 0.00002 Pa.toolBox for acoustics will be updated over time with moregreatfeatures.
