beat frequency
Science; Acoustics

If two vibration components are quite close together in frequency and if they are present at the same time at the same place, they will combine in such a way that their sum will ...

acoustic phase coefficient
Science; Acoustics

Imaginary part of the linear exponent of sound propagation.

average
Science; Acoustics

In acoustics where dB levels are extensively used, average may not mean adding up the values and then dividing by the number of samples.

interference
Science; Acoustics

In acoustics, occurs when two sound waves interact and form a resultant wave of greater or lower amplitude.

leakage
Science; Acoustics

In an FFT analyzer, the input signal is recorded in time blocks, called time records, and individual spectra are computed from each block of data. Because the input signal period ...

sideband
Science; Acoustics

In frequency domain functions, pairs of frequencies with similar amplitude that appear equally spaced on either side of a center frequency - produced by modulation.

force (F)
Science; Acoustics

In physics, a force is whatever can cause an object with mass to accelerate. Force has both magnitude and direction, making it a vector quantity is defined as the rate of change ...
