Amplified nightclub music can cause hearing damage. Changes in hearing thresholds can lead to excessive exposure to any type of sound. Regardless of whether the sound is pleasant or not, or the genre of music, the degree of noise-induced hearing loss (NIHL) depends on the intensity and frequency characteristics of the noise, as well as its duration and intermittency of the exhibition. Individual genetic and environmental factors also play an important role (Bovo, Ciorba, & Martini, 2007). Hetu and Fortin (1995) studied the characteristics of highly amplified music in nightclubs from a psychoacoustic and phenomenological perspective. They found that amplified music is characterized by strong pulsations (≈2 Hz), a narrow dynamic range, and a tilted spectrum with peak energy in the third of an octave centered at 63 Hz. This spectrum, according to Hetu and Fortin ( 1995), corresponds to the high free-field threshold curve of 80 dB. Temporary threshold shift (TTS) can be easily predicted. TTS can be considered a slow trend at the onset of permanent hearing damage (Dobrucki, Kin, & Kruk, 2013). Exposure to loud noise damages the organ of Corti in the cochlea and subsequently leads to elevated thresholds. There are two types of damage. Immediate permanent hearing loss may be the result of very short exposure to extremely loud noise above 140 dB. This sound energy can cause significant vibration and detachment of the basilar membrane, with the middle ear structure also potentially involved, resulting in additional conductive losses (Clark & ​​Bohne, 1999). Compared to the second type of damage, this type of insult may be more likely to affect the supporting structures of the organ of Corti, Reissner, and tectorial membranes....... middle of article. .....domized trial of 1,000 students.
