The earliest precise experimental value for the speed of sound, obtained at the Academy of Sciences in Paris in 1738, was 332 metres per second incredibly close to the presently accepted value, considering the rudimentary nature of the measuring tools of the day.
Musicians with knowledge of the Clavinet sound obtained the highest d score, 58%, 3% lower than that obtained with the previous model, showing an increase in sound quality with the current model.
Results from measures of speech intelligibility, pitch perception, and subjective appreciation of sound obtained with the two current steering strategies and a standard strategy are compared in 9 adult cochlear implant users.
According to him, the sound obtained was "a little unorthodox" and therefore, he tried to refine it.
The CON-sf song is similar to a synthetic sound obtained by amplitude-modulating coloured noise using the temporal envelope of the song, with the exception that CON-sf additionally preserves local spectral quality.
Environmental sounds were obtained from online sound databases (e.g. www.sonomic.com; www.soundrangers.co.uk).soundrangers.co.uk
In perhaps the most comprehensive study [31], ratings of 145 environmental sounds were obtained representing various categories of naturally occurring environmental sounds (e.g., impact sounds, water sounds, ambient sounds) on 20 7-point bipolar scales.
Sound recordings of artificial sounds were obtained between October 2007 and December 2007.
