What is the frequency response of a microphone?

Frequency response defines the range of sound that a microphone can reproduce and how its output varies within that range. The frequency response is the most significant factor in determining the sound signature of a microphone. The frequency response of a mic is represented graphically by a response curve.

How does a sine sweep work?

Sine Sweep Process

During a sine sweep test, a vibration shaker pans, or “sweeps,” through a range of frequencies. The motion of the shaker is sinusoidal; however, the frequency of the vibration increases or decreases throughout the test.

What is a frequency sweep used for?

Frequency sweeps generally serve the purpose of describing the time-dependent behavior of a sample in the non-destructive deformation range. High frequencies are used to simulate fast motion on short timescales, whereas low frequencies simulate slow motion on long timescales or at rest.
