Acoustic vents play a critical role in electronic devices — particularly in audio equipment that is designed to keep internal components safe from dust, humidity and other contaminants, but at the same time needs to allow sound waves through as cleanly as possible. These vents are essential for keeping the appropriate day-to-day lifestyle and life of tools including cellular phone, earphone as well as audio speakers. They assist in balancing the internal and external air pressure, preventing damage to speaker and microphone diaphragms. To illustrate this, GORE® Acoustic Vents are recognized for their ability to provide superior fluid and fine particulate protection without sacrificing acoustic performance.
