The correct answer is that if the noise and the music volume are the same, then the chance of causing hearing damage is the same. Of course, music sounds very comfortable, while noise sounds harsh, so it puts a lot of physical pressure on you.

Noise is a sound we don't like. The sound of a new child playing the violin can be painful for you. However, when the teacher plays the same violin, the music will be pleasing to you. We know that a violin is supposed to produce a constant range of frequencies, so the frequency is irrelevant to whether it is noise or not. The ancient Greek mathematician and philosopher Pythagoras discovered that two frequencies and their ratios defined music or noise. He found that if their ratio could be reduced to something as simple as 3:7, the sound was pleasant music. If it was a complex ratio that could not be simplified, such as 201:388, under such conditions, the sound was harsh, unpleasant noise.

Listening to your favorite music is enjoyable, but listening to your favorite music at too high a volume or for too long.  Will lead to "Hearing Fatigue" or "Temporary Threshold Shift (TTS)."  TTS is a warning sign that your hearing may become severely impaired.

When you listen to loud music, and after a while, you feel the music becomes quieter. This is a sign that your hearing has become sluggish due to fatigue. Usually, you compensate by turning up the volume. After a while, this happens again; you make it louder again until it becomes a vicious cycle. And you go from "Temporary Threshold Shift (TTS)" to "Permanent Threshold Shift (PTS)," and your hearing is too damaged to recover.

However, even if you don't increase the volume of your music. If you don't stop to give your ears enough time to rest. Hearing fatigue damage can still occur and continue until it becomes "Permanent Threshold Shift (PTS)." Which is a bad situation that all music lovers can face. The way to avoid this is not to listen to music at too high a volume. If you cannot control the music's loudness, you must wear proper hearing protection earplugs.

The ideal musical earplug must be able to fulfill these requirements.

● Protects your hearing from suffering damage in extremely loud environments.

The ACS PRO custom music earplugs are made of medical-grade soft silicone and fit snugly into the ear canal when worn. As your ear canal deforms due to physical movement, the PRO silicone earplugs will follow this deformation to maintain a good seal. They are allowing the ACS PRO filters to process all sound entering the ear canal.

Over the past 26 years, ACS has developed PRO music filters that meet all of the above requirements. The ACS PRO filters can handle music volumes, from small indoor gigs to large concerts, nightclubs, electronic parties.

All PRO music filters have flat attenuation characteristics and do not alter the original audio structure at all. You'll never have to worry about what you hear when you're listening to or playing music with ACS PRO custom earbuds.

The ACS PRO filter has an exclusive bi-directional conduction function that allows air and sound inside the earplug sealed ear canal to escape through the filter. It is not stuffy when worn for long periods. It also minimizes the blocking effect caused by earplugs blocking the ear canal, so you can hear your natural voice, whether you're just communicating or singing.

Because of these features, ACS PRO is the hearing protection earplug of choice for world-renowned DJs, professional musicians, audio/recording engineers, music scene workers, and many hardcore music fans.
