To guide building design, a proper understanding of people’s annoyance to tonal office noises is needed. It is known that sound quality plays a role in annoyance perception. This paper develops and refines a metric model to predict perceived annoyance for office noises. The model was built based on subjects’ average annoyance ratings for 222 5-second sounds. Test sounds include tonal sounds with different broadband sounds, different level and frequency tones, and a group of harmonic sounds. Thirty subjects with a normal hearing participated in the test and were asked to rate the level of annoyance. Results show that loudness, tonality, and sharpness all turn out to play a role in annoyance perception. Tone-to-Noise Ratio is selected as the tonality metric for a better model performance. Refinements are introduced to Tone-to-Noise Ratio by integrating different tonal components’ contributions, adding hearing threshold to Tone-to-Noise Ratio, and limiting the metrics contributions to deal with the outliers in the model.
