The science of sound is called as Acoustics. It involves everything, including sound production, control, transmission, reception and also the effects of the sound. Different types of sounds affect us in many different ways. The science of acoustics plays a crucial role in earth sciences, engineering, life sciences and the arts. Acoustics finds usage not just in designing musical instruments, auditoriums, concert and movie halls, home theatres but also in the hearing aids and the ultrasounds for medical imaging. Beyond these commonly known applications, acoustics helps in finding the natural oil and gas reserves, study earthquakes and climate change.
