Title Confirmation of noise exposure levels by analysis of the audiometric data in long service underground train drivers
Bibliographic information Autumn 1989, Vol. 39, No.3, p.107-110. 5 ref.
Abstract The results of 40 audiograms from otologically normal long-term underground train drivers were compared with the predicted values published by the National Physical Laboratory tables (Robinson and Shipton, 1977). The age-corrected hearing threshold levels were plotted as an arithmetic probability at varying frequencies and compared with the corresponding predicted distributions. The results indicate that London Transport Underground train drivers are subjected to a noise level of less than 85dB(A)LEQ(8h), which substantiates the surveyed noise levels.
