Abstract: The sine sweep is one of the most effective methods for measuring room impulse responses; however, ambient room noise or unpredictable impulsive noises can negatively affect the quality of the measurement. This study evaluates four different variants of sine sweeps techniques for their resilience to noise when used as an excitation signal in room impulse response measurements: linear, exponential, noise whitened, and minimum noise. The result shows that in a pseudo-anechoic environment, exponential and linear sine sweeps are most resilient to impulsive noise among the four sweeps, while none of the evaluated sine sweeps are resilient to impulsive noise in an acoustically untreated room. Additionally, it is shown that minimum noise sine sweeps are most resilient to ambient noise.

This study evaluates four different variants of sine sweeps techniques for their resilience to noise when used as an excitation signal in room impulse response measurements: linear, exponential, noise whitened, and minimum noise. The result shows that in a pseudo-anechoic environment, exponential and linear sine sweeps are most resilient to impulsive noise among the four sweeps, while none of the evaluated sine sweeps are resilient to impulsive noise in an acoustically untreated room.
