AbstractThis paper reports the results of an initial experiment to evaluate the additional annoyance caused by varying amounts of low frequency rumble sounds from heating, ventilating, and air conditioning (HVAC) systems. HVAC noises were simulated with various levels of low-frequency sound and varying amounts of amplitude modulation of the low-frequency components. Subjects listened to the test sounds over headphones and adjusted the level of the test sounds to be equally annoying as a fixed neutral reference sound. The results indicated that annoyance is influenced by both the level and the amplitude modulation of the simulated HVAC rumble sounds. A procedure that incorporates these two factors is suggested for predicting the additional annoyance of HVAC sounds containing rumble.
