Angry Noise Detector

Elevated workplace or other noise can cause hearing impairment, hypertension, ischemic heart disease, annoyance, and sleep disturbance.

Noise exposure also has been known to induce tinnitus, hypertension, vasoconstriction, and other cardiovascular adverse effects.

This App uses the flat and friendly design style, precise sampling and computational method, make you can use the microphone sensor of iPhone (or earphone), to survey precisely the noise level of some environment (or object) for a period of time. It may provide the comprehensive careful noise condition information for yours life and the physical and moral integrity. Has it, uses it, you can obtain benefits a great deal!

[Function Introduction]
1. Use the microphone sensor, examine the noise condition of a period of time.
2. Based on the current noise level, change color from quiet green to angry red, just like us humans.
3. Give the statistic information of noise intensity in dB SPL, calculate maximum value, minimum value and mean value.
4. Based on the current noise level, give the abundant prompt information.
5. Using the headset microphone (Ear Pods), can improve the measurement accuracy. To survey some single object, you may use the earphone approach it.

[Operating Introduction]

3. Click the top LOGO, switch the waveform display style.
4. The default action is getting the average noise level for a period of time, if you want to measure the noise level of the short sound, can open the scroll waveform style, click the center dial again, and observe the peak value.

[Use scene]
1. Purchases a house, examines its interior and the periphery noise condition.
2. Purchases a car, examines its sound-insulated effect, and examines the car noise in the process of driving.

Not intuitive

This app measures the AVG decibel, not a running display of the current noise, which is kinda useless. It might measure the current noise, but it is so hard to use and the instructions so poorly written that I’m not sure.

Worst app ever!

I paid for this app and it does not work At ALL! Every time you open it, it just shuts off! USELESS!
I gave it one star because it would not allow me to give it a zero.
