Abstract
The current subjective system of classifying floor impact sound levels is insufficient and requires more accurate classification criteria Statements describing floor impact sound are collected and used to create a new statement-based scale using the equal-appearing interval scale method. An auditory experiment was conducted measuring annoyance levels and using the new statement scale to establish a floor impact noise standard in apartment buildings. Floor impact sounds from impact ball were recorded; the impact sound pressure level (SPL) and the temporal decay rate (DR) were analyzed. For the experiment, A-weighted exposure levels of the heavyweight floor impact sounds ranging from 34 to 73 dB were evaluated at 3 dB intervals. Participants used a 7-point verbal scale (annoyance level) and the new 7-pt statement scale. Consequently, a floor impact sound classification based on response statement was proposed PACS no. 43.40.+s, 43.58.+z, 43.66.+y
