Noise Shield

NoiseShield is your personal sound safety assistant. It continuously monitors ambient noise in your environment using your device’s microphone and alerts you when sound levels reach dangerous thresholds.
Whether you're in a city, a concert hall, a factory, or even at home using TV, NoiseShield helps you make informed choices to protect your hearing—before it’s too late.


Why NoiseShield Matters

Hearing loss caused by noise exposure is entirely preventable, yet it affects millions of people globally.

According to the Centers for Disease Control and Prevention (CDC):
“Noise above 70 dB over a prolonged period may start to damage your hearing. Sound at or above 120 dB can cause immediate harm.” (Source: CDC)

The World Health Organization (WHO) states:
“Over 1 billion young people (aged 12–35 years) are at risk of hearing loss due to recreational exposure to loud sounds.” (Source: WHO)

From daily commutes and loud workplaces to concerts and headphone use, exposure to high sound levels adds up. NoiseShield gives you the tools to monitor and manage that risk in real time.
