Response from developer

Dear Zenoran, sorry to hear you have problem using Noise Control. Please check you iPhone Settings and see if you have enabled Noise Control to access your microphone.

Did not work.

This app simply did not work. The yelling of four seven year old boys didn’t set it off.

Bought for classroom use

I have one particularly noisy class and when I read about this app making a shhing noise at a certain level of noise. I thought it would be great for this group. However, no matter how high the volume control is on my phone, the shhh the app makes is too low to be heard above the noise made by the class.

Excellent

I am using this as a classroom management tool in my middle school classroom. My students have responded positively to this app.

I recommend plugging your phone into a pair of computer speakers because the warning sound is too low on the phone speaker.
