How do you find the impulse response of a room?
Rxy(t) = δ(t) * h(t) = h(t). Therefore, the transfer function, i.e., the impulse response of a room can be calculated by computing the cross-correlation between the original MLS and its recording in the room.
How do you measure impulse response?
The simplest way of measuring an impulse response is often the use of an impulsive source signal such as a clap of your hands, a balloon or a blank pistol. By selecting External Impulse, the response to an impulsive signal is simply recorded without any subsequent processing.
What is impulse response in room acoustics?
What Is Impulse Response? 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.
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.
