About

To help users protect their hearing, this application can monitor the dB SPL (Sound Pressure Level) output of the headphones in real-time, allowing users to be aware of the potential impact of the current volume on their hearing.

Additionally, users can set a maximum sound pressure level limit to ensure that the headphone volume does not exceed a safe threshold (e.g., 80 dB), effectively preventing hearing damage.

Hearing Loss is Irreversible and Untreatable.

According to a report by the World Health Organization (WHO) on hearing health, hearing loss caused by noise exposure is irreversible. Excessive noise exposure permanently damages the hair cells in the ear. Once damaged, these hair cells cannot regenerate or be repaired, leading to permanent hearing loss. Common symptoms of hearing loss include muffled hearing, difficulty understanding conversations, and tinnitus, which can significantly impact the quality of life. Therefore, protecting your hearing and avoiding exposure to high levels of noise is crucial.

dB SPL (Sound Pressure Level) is the standard measure of sound intensity. It represents the ratio of the sound pressure to a reference sound pressure, typically measured in decibels (dB). 0 dB SPL corresponds to the faintest sound the human ear can hear, while a normal conversation is around 60 dB SPL.

Prolonged exposure to sound levels above 85 dB SPL can cause irreversible hearing damage. Short-term exposure to sound levels exceeding 100 dB SPL (such as at concerts or noisy construction sites) can also cause immediate hearing damage. To protect your hearing, it is recommended to keep the sound pressure level in your environment below 80 dB SPL and avoid prolonged exposure to loud environments.
