“…Floor impact sound has been reported as the most irritating noise source in residential buildings (Langdon et al, 1981(Langdon et al, , 1983Kimura et al, 1994;Jeon, 2001). People in a building encounter various floor impact sounds from the upper floor in their daily lives: sounds created by human footsteps and jumping and running with or without shoes.…”

This study investigated the relation between annoyance and single-number quantities to rate heavy-weight floor impact sound insulation. Laboratory experiments were conducted to evaluate the subjective response of annoyance resulting from heavy-weight floor impact sounds recorded in wooden houses. Stimuli had two typical spectra and their modified versions, which simulate the precise change in frequency response resulting from insulation treatments. Results of the first experiment showed that the Zwicker's percentile loudness (N(5)) was the quantity to rate most well annoyance of heavy-weight impact sound over a wide sound level range. The second experiment revealed that arithmetic average (L(iFavg,Fmax)) of octave-band sound pressure levels measured using the time constant "fast" and Zwicker's percentile loudness (N(5)) much better described annoyance by the precise change in the sound spectrum attributable to insulation treatments than Japanese standardized single-number quantities (L(i,Fmax,r), L(iA,Fmax), and L(i,Fmax,Aw)) do. Japanese standardized single-number quantities using the A-weighting curve as a rating curve were found to be excessively influenced by the 63 Hz octave-band sound level and have the great sound level-dependences in the relation with subjective ratings.

“…Electronic mail: john.bradley@nrc-cnrc.gc.ca satisfaction. [9][10][11][12][13] Vian et al 14 conducted subjective listening tests in the laboratory to assess the adequacy of a French rating method for sound isolation in buildings based on an A-weighted level difference and using a pink noise source signal. They concluded that annoyance responses were most strongly correlated with A-weighted level differences limited to include information only in the 1 / 3-octave bands from 125 to 4k Hz.…”

This paper reports on an evaluation of ratings of the sound insulation of simulated walls in terms of the intelligibility of speech transmitted through the walls. Subjects listened to speech modified to simulate transmission through 20 different walls with a wide range of sound insulation ratings, with constant ambient noise. The subjects' mean speech intelligibility scores were compared with various physical measures to test the success of the measures as sound insulation ratings. The standard Sound Transmission Class (STC) and Weighted Sound Reduction Index ratings were only moderately successful predictors of intelligibility scores, and eliminating the 8 dB rule from STC led to very modest improvements. Various previously established speech intelligibility measures (e.g., Articulation Index or Speech Intelligibility Index) and measures derived from them, such as the Articulation Class, were all relatively strongly related to speech intelligibility scores. In general, measures that involved arithmetic averages or summations of decibel values over frequency bands important for speech were most strongly related to intelligibility scores. The two most accurate predictors of the intelligibility of transmitted speech were an arithmetic average transmission loss over the frequencies from 200 to 2.5 kHz and the addition of a new spectrum weighting term to R(w) that included frequencies from 400 to 2.5 kHz.

“…In London, the most frequently heard noises were footsteps and talking/shouting. Earlier studies in the UK reported that music, television, radio, and footfalls on the floor were the most commonly heard noises [43], and that footsteps, music, television, and radio were most frequently heard from above with music, television, radio, and voices being heard the most from the side [46]. One possible reason that television and radio are no longer as commonly heard could be due to increased listening on headphones and the decrease in real-time television viewing, such that viewing times in adjacent habitable rooms are no longer synchronised [55].…”

“…If the respondents confirmed that they heard a specific noise source they were asked to rate their annoyance with that source. A total of ten major noise sources were selected based on previous studies [43][44][45][46] and these were classified as either structure-borne or airborne sources. Structure-borne sources were footsteps (including jumping and running), dropped objects, movement of furniture, door closing, home appliances (e.g., a washing machine, dishwasher, tumble dryer, and vacuum cleaner), and water installations (e.g., sounds from pipes, plumbing, flushing toilets, showers, and baths).…”

This study investigated people’s attitudes towards noise inside their homes. Online questionnaire surveys were conducted in Seoul, London, and São Paulo. The questionnaire was designed to assess annoyance caused by noise from neighbours and environmental noise (transportation). Information was also collected on situational, personal, and socio-demographic variables. Respondents that were more annoyed by outdoor noise inside their dwelling reported higher neighbour noise annoyance. In Seoul, neighbour noise was found to be more annoying than outdoor noise, and those with higher noise sensitivity reported higher annoyance towards neighbour noise. However, neighbour noise and outdoor noise was found to be equally annoying in London and São Paulo. For neighbour noise, the average percentage of respondents hearing structure-borne sources compared to airborne sources differed in each city. Most neighbour noise sources in São Paulo gave rise to higher annoyance ratings than Seoul and London. Education and income levels had a limited effect on annoyance and coping strategy. Annoyance with indoor noise from neighbours was found to have stronger relationships with cognitive and behavioural coping strategies than outdoor noise annoyance.
