hörselnivåer

Hörselnivåer refer to the level of sound intensity or loudness that an individual is capable of perceiving. The concept of hörselnivåer is fundamental to the study of acoustics and audiology, as it can influence an individual's ability to discern and process sound.

In humans, hearing is a process that occurs within the range of approximately 20 Hz to 20,000 Hz. Within this range, sound is perceived at varying levels of loudness, typically measured in decibels (dB). Hörselnivåer can be categorized into various levels, from very soft to extremely loud, with corresponding dB values.

The World Health Organization (WHO) defines tönenivåer in the following classifications:

- Lägsta (nära det Kantonska tröns praktissesquellepunkt its – n)än

- Låga

- Medelhög

- Höga

- Väldigt höga

For each category, specific sound intensity levels are associated, as follows:

People with normal hearing perception can hear sounds within the range of 0 dB to 85 dB without any issues. On the other hand, exposure to sound levels greater than 85 dB can be stressful or even painful for the individual and may also pose health risks when exposure is prolonged. It is generally agreed upon that exposure to sounds that exceed 85 dB should be as short and rarely necessary as possible.
