Abstract:
The discomfort brought to students by airplane noises recorded on magnetic tape was studied during classes. During 18 periods, students hearing altogether 128 airplane noises, gave after each noise a score between 1 and 6 according to their subjective evaluation of the discomfort they experienced. The variables in the airplane noises which were used gave the following results 1 The discomfort increases almost linearly with the auditory level expressed in dbA or in PN db this is true of the two auditory spectra studied DC-8 and Caravelle. 2 The discomfort increases with the duration of noises. 3 For identical noise levels, expressed in dbA, the acoustical spectrum with high pitch predominance Caravelles landing led to a stronger discomfort than the spectrum with low pitch predominance taking-off of the DC-8. 4 The discomfort was the same during periods with 5 or 6 airplane noises as during periods with 10 or 11. 5 The repetition of the same noises led to a low but significant decrease in the discomfort experienced.
