Catalog Course Description
This course is a study of Acoustics principles and the physics of sound. It includes sound propagation, hearing and sound perception, room resonances, acoustic calculations, studio design and acoustical treatments. 54 lecture hours.
Course Objectives
- Identify the sonic properties of materials used in live venues and recording studios
- Identify properties that affect room acoustics and listener perspective
- Correlate the properties of room acoustics with effects processors
Major Course Content
- Sound Propagation – The Waveform Model, sound measurement, frequency amplitude and wavelength.
- Hearing and Sound Perception – human hearing and psychoacoustics.
- The Physics of Sound – sound behavior, reflection, reverberation, absorption, refraction and diffusion.
- Controlling Noise – acoustic isolation, de-coupling and transmission loss.
- Room Modes – resonances in enclosed spaces, determining modal frequencies.
- Acoustics of the Recording Studio – interior treatments, controlling reflections, studio and control room acoustical treatment.
- Acoustic Calculations – calculating sound pressure, wavelength, reverberation times and modal frequencies.
