In acoustics and audio, a transient is a high amplitude, short-duration sound at the beginning of a waveform that occurs in phenomena such as musical sounds, noises or speech. [1] [2] Transients do not necessarily directly depend on the frequency of the tone they initiate. It contains a high degree of non-periodic components and a higher ...
Transient noise pulses consist of a relatively short pulse followed by decaying low frequency oscillations. The initial peak is often due to an impulse interference , and the following oscillations are due to resonance on the channel that received the initial pulse.
Transient modelling, a way of looking at a process with the primary criterion of time, observing the pattern of changes in the subject being studied over time. Transient response, the response of a system to a change from an equilibrium or a steady state. Transient (acoustics), a high-amplitude, short-duration sound at the beginning of a waveform
Onset refers to the beginning of a musical note or other sound. It is related to (but different from) the concept of a transient : all musical notes have an onset, but do not necessarily include an initial transient.
Example of airborne and structure-borne transmission of sound, where Lp is sound pressure level, A is attenuation, P is acoustical pressure, S is the area of the wall [m²], and τ is the transmission coefficient. Acoustic transmission is the transmission of sounds through and between materials, including air, wall, and musical instruments.
Analysis of sound and acoustics plays a role in such engineering tasks as product design, production test, machine performance, and process control. For instance, product design can require modification of sound level or noise for compliance with standards from ANSI, IEC, and ISO. The work might also involve design fine-tuning to meet market ...

Sound is defined as "(a) Oscillation in pressure, stress, particle displacement, particle velocity, etc., propagated in a medium with internal forces (e.g., elastic or viscous), or the superposition of such propagated oscillation.
