INFRASTRUCTURE Shall have full time services of ENT Surgeon and Audiologist Shall have facilities for Pure tone Audiogram and Impedance Audiogram Shall have sound proof room to conduct Audiometry.
Pure tone air conduction audiometry tests are common audiometric exams performed and required in the United States by OSHA.19 Pure tones between 500 and 8000 Hz are presented at varying levels to determine an individual’s pure tone detection thresholds (the quietest sound level detected above the audiometric zero).
Pure tone detection thresholds (the quietest sound level detected above the audiometric zero), or average hearing thresholds, were analyzed as a continuous variable.
Pure tone detection thresholds are plotted against frequency of pure tones conducted during the exam (Figure 5).
Pure tone air conduction audiometry tests were conducted for hearing thresholds at 500 Hz, 1000 Hz, 2000 Hz, 3000 Hz, 4000 Hz, 6000 Hz, and 8000Hz in both left and right ears following ISO 8253M1: 2010 methodology.48 Personal protective hearing equipment has been available (and mandatory) since the plant started operations.

Pure tone means any sound which can be distinctly heard as a single pitch or a set of single pitches. For the purposes of this Ordinance, a pure tone shall exist if the one-third octave band sound pressure level in the band with the tone exceeds the arithmetic average of the sound pressure levels of the two contiguous one-third octave bands by 5 dB for center frequencies of 500 Hz and above and by 8 dB for center frequencies between 160 and 400 Hz and by 15 dB for center frequencies less than or equal to 125 Hz.

Pure tone means any sound that can be distinctly heard as a single pitch or a set of single pitches.
