This study investigates how tonality influences the perceived annoyance of heat pump noise. Heat pumps produce noise mainly from fans and compressors. These noises often contain prominent tonal components that can make them particularly disturbing. In this work, four fundamental heat pump noise samples were divided into three frequency bands, and their tonal features were […]

With the increasing usage of heat pumps in residential areas, their noise emissions have become a growing concern. One potential solution is masking, where additional sounds modify the perception of unwanted noise. This study investigated the effects of different types of maskers (pink noise, high-pass filtered pink noise, and water sound) and masker locations on […]
