Figure 2: Result of the alterations in the SNRs at studied frequencies in the right and left ears in case group exposed to noise level (88 dBA). (A–D) The mean values of SNR in the right and left ears at similar frequencies. (A) The mean SNR values in the time interval of 7:30–8:00 AM. (B) The mean SNR values in the time interval of 10:30–11:00 AM. (C) The mean SNR values in the time interval of 13:30–14:00 PM. (D) The total of mean SNR values in the three time intervals
