[Decreased sound tolerance and tinnitus]
Summary
This review explores decreased sound tolerance, including hyperacusis and phonophobia, often associated with tinnitus. It focuses on hyperacusis as a prevalent symptom impacting concentration and emotional well-being.
Area of Science:
- Audiology
- Neuroscience
- Otolaryngology
Context:
- Decreased sound tolerance, encompassing hyperacusis and phonophobia, is frequently linked to tinnitus.
- Tinnitus is a subjective auditory perception without external stimuli, often accompanied by hearing loss or psychological distress.
- Associated symptoms include sleep disturbances, annoyance, anger, anxiety, depression, and difficulty concentrating.
Purpose:
- To review concepts related to decreased sound tolerance.
- To specifically focus on hyperacusis as a common symptom within this category.
Summary:
- Decreased sound tolerance involves conditions like hyperacusis and phonophobia.
- Tinnitus, a phantom auditory sensation, frequently co-occurs with decreased sound tolerance.
- Hyperacusis is highlighted as a particularly common symptom requiring further investigation.
Impact:
- Enhances understanding of the relationship between tinnitus and sound tolerance issues.
- Provides a foundation for research into hyperacusis management.
- Improves clinical awareness of associated psychological and cognitive impacts.

Sound Intensity Level
Humans perceive sound by hearing. The human ear helps sound waves reach the brain, which then interprets the waves and creates the perception of hearing. The loudness of the environment in which a person is located determines whether they can distinguish between different sound sources.
The human ear can perceive an extensive range of sound intensity, necessitating the use of the logarithmic scale to define a physical quantity—the intensity level. It is a ratio of two intensities and hence a...

Perception of Sound Waves
The human ear is not equally sensitive to all frequencies in the audible range. It may perceive sound waves with the same pressure but different frequencies as having different loudness. Moreover, the perception of sound waves depends on the health of an individual's ears, which decays with age. The health of one's ears may also be affected by regular exposure to loud noises.
The pitch of a sound depends on the frequency and the pressure amplitude of the source. Two sounds of the same frequency...

Sound Intensity
The loudness of a sound source is related to how energetically the source is vibrating, consequently making the molecules of the propagation medium vibrate. To measure the loudness of a source, the physical quantity of interest is the intensity. This is defined as the energy emitted per unit of time per unit of area perpendicular to the sound wave's propagation direction. Since the total energy is greater if the source vibrates for a longer duration and over a larger area, dividing the emitted...
Hearing
When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.
Desensitization and Tachyphylaxis
Tachyphylaxis is described as a rapid decrease in response to a drug after repeated or continuous administration of the same drug dose. It is a phenomenon where the body becomes less responsive to a particular substance or intervention over time, requiring higher doses or stronger interventions to achieve the same effect. It results from adaptive changes in the body's receptors, signaling pathways, or physiological processes that occur in response to prolonged exposure to a stimulus.
