Sound waves for music tech

What are standing waves?

Standing waves are waves that remain in a constant position, formed by the interference of two waves traveling in opposite directions.

What is the attack phase in sound?

The attack phase is the initial part of a sound's envelope, where the sound reaches its peak amplitude.

What is decay in sound?

Decay is the phase following the attack in a sound's envelope, where the amplitude decreases after the initial peak.

What is sustain in sound?

Sustain is the phase in a sound's envelope where the sound maintains a steady amplitude after the decay phase.

What is release in sound?

Release is the final phase in a sound's envelope, where the amplitude decreases to zero after the sustain phase.

What is the threshold of hearing?

The threshold of hearing is the lowest sound level that can be heard by the average human ear, typically around 0 dB.

What is the threshold of pain?

The threshold of pain is the sound level at which sound becomes painful to hear, typically around 120 to 140 dB.
