A conductive loss results from damage in the ear before the cochlea. Typically, a conductive loss can be successfully treated with either pharmaceutical or surgical remedies. It is important to be aware of the nomenclature when researching the subject. Although this probably occurs for many reasons, hearing loss due to general physiologic wear and tear in the cochlea is exacerbated by regular overexposure to loud sounds. With repeated exposure to loud sounds over time, the cell dies and eventually the adjacent hair cells and supporting cells become vulnerable.
Cell death affects adjacent cells, resulting in functional deficits across frequencies.
It has also been noted that hearing loss from overexposure to loud sounds can also result in nonauditory problems. 6 Examples include, but are not limited to, illness, headache, fatigue, insomnia, irritability, neuroticism, hypotension, hypertension, cardiac disease, colitis, endocrine disorders, biochemical disorders, and ulcers. As stated previously, IEMs offer many benefits from the audio engineer's point of view. The overall fidelity due to the proximity of the amplifier to the eardrum is a significant improvement over wedge monitor systems. An experienced engineer can achieve sound quality with IEM systems that rival pro-studio headphones in dynamic range, breadth of frequency response, and clarity.
