How can a sine sweep be useful when measuring a room?
The use of sine sweeps is a robust method to measure room impulse responses. One particular advantage is that the frequency spectrum of the excitation signal can be con- trolled in the time domain – by changing the rate of fre- quency change – while keeping the amplitude of the signal virtually constant over time.
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.
What is room impulse responses?
The room impulse response is the transfer function between the sound source and microphone. In order to recover the original sound source, the received microphone signal can be convolved with the inverse of the room impulse response function.
What is a sine sweep?
A sine sweep is a sine function that gradually changes frequency over time. The sine sweep can also be called "sinusoidal sweep," "frequency sweep", or "chirp".
