What does sine sweep mean?
The essence of a sine sweep test is that the base excitation input consists of a single frequency at any given time. The frequency itself, however, is varied with time. The sine sweep test may begin at a low frequency and then sweep to a high frequency, or vice-versa.
How do you measure the impulse response of a room?
The measurement of impulse responses inside of a room or a theatre is a critical task in architectural acoustics. The impulse responses are usually measured using either Exponential Sine Sweep (ESS) or Maximum Length Sequence (MLS) signals.
