I didn’t know Google made an app for hearing in noisy places — it’s been on my phone the whole time

Hearing a single voice in a crowded room can be difficult for anyone, even if the person speaking is right beside you. If you’re in an extremely loud environment, like a sporting event or concert, maintaining a clear conversation becomes nearly impossible. For people with difficulty hearing, using earbuds to make a phone call can sound clearer than trying to hold an in-person discussion in a noisy room. Luckily, your Android phone can help. Google makes a little-known app called Sound Amplifier for the sole purpose of loudening sounds so they are easier to hear.
