Using data from a realistic experiment conducted using recorded traffic
sounds, the relationship between indicators of magnitude, spectrum,
and temporal evolution of the sonic environment and the reported
annoyance are analyzed. The exposure is characterized by the binaurally
recorded overall indoor sound. It is found that a series of parameters
derived from multiple linear models related to the temporal and spectral
structure of the sound pressure level produces better models than
the overall indoor A-weighted equivalent noise level. The descriptors
thus complement this indicator, at least when exposure is based on
overall indoor sound. Principle components amongst the exposure indicators
studied relate to the detectability of the sound indoors and to the
typical temporal difference between road and rail traffic. Linear
models based on these indicators also outperform models based on
source related façade.
