We are involved with research leading to noise prediction from aircraft jets,
wind turbines, domestic fans and vacuum cleaners. These predictions are
available as (generally ascii) data files. It would be extremely useful to
have a reliable way of synthesising the predicted noise output so that we
could play it as a sound file. This would help us develop less annoying
It is not just loudness that determines how annoying noise is. Annoyance also
depends on the frequencies involved, the background noise level and what, if
any, patterns the brain can detect in the noise. So hearing the sound is very
important in determining how annoying it is.
In this project we will develop a sound synthesis software package
(using either Python or MATLAB) that would help us produce realistic sound
simulations for given predicted, or partially measured, noise sources from
aircraft and domestic fans and vacuum cleaners.
