Acoustics is the study of all mechanical waves in gases, liquids and solids. These mechanical waves can include vibrations, sound, ultrasound and infrasound. A scientist which works in the field of acoustics is called an acoustician. Someone working in the field of acoustic technology may be called an acoustical engineer.
Hearing is one of the most crucial means of survival in the animal world. Speech is one of the most distinctive characteristics of human development and culture. The science of acoustics affects many facets of human society. The fields can range from music, medicine to architecture and industrial production.
Acoustics revolves around the generation, propagation and reception of mechanical waves and vibrations. Any acoustical event or process has five main steps. These steps include cause, generating mechanism (transduction), acoustic wave propagation, reception (transduction) and effect.
Physicists and acoustic engineers discuss sound pressure levels in terms of frequencies. This is based on how our ears interpret sound. What vertebrates experience as higher or lower pitch sounds are pressure vibrations having a high or lower number of systems per sound.© BrainMass Inc. brainmass.com June 26, 2019, 1:52 am ad1c9bdddf
