80 db: Around 5 hours and 30 minutes a day.Consider using hearing protection or moving to a quieter area.Īpple Watch also shares examples of noise levels/time exposure that can lead to temporary hearing loss: Repeated, long-term exposure to sounds above 80 dB can lead to permanent damage. So what’s a harmful decibel level? That depends on the amount of time you’re exposed along with the level of noise. That makes it much easier to prevent hearing damage and loss by knowing when to turn down the volume, use ear protection, or leave a loud environment. Thankfully, iPhone and Apple Watch feature both ambient (environmental) and headphone decibel monitoring that are quick and easy to use, including noise threshold warnings. In the US, an estimated 37.5 million adults have trouble hearing, and men are believed to be twice as likely to experience hearing loss as women (via the National Institute for Deafness and Other Communication Disorders).

The source code for Decibel Meter using Sound Module & Arduino with LCD is given below. Remove the microcontroller from the board and insert it in the circuit given above. The program for both the circuit is the same.įor the above circuit, a fresh new ATmega328 microcontroller with a bootloader is inserted on Arduino Board, and code is uploaded. Or simply assemble the circuit as shown in the figure. Either use Arduino Board for this project. The input-output pins are not selected on the behalf of Atmega328 pins but on the behalf of Arduino analog and digital pins. The ATmega328 microcontroller is programmed using the Arduino language. You can check Sound Sensor Datasheet for more details When the sound level exceeds the setpoint, an LED on the module is illuminated and the output is sent low. The sound level setpoint is adjusted via an onboard potentiometer. Sound is detected via a microphone and fed into an LM393 op-amp. The sound detection sensor module for Arduino detects whether the sound has exceeded a threshold value. The simple specifications of sound module from left to right first pins are as follows: ➡ Can be used for the sonic lamp, with photosensitive sensors act as sound and light alarm, also can be used in the occasion of voice control and sound detection. ➡ Output low level and the signal light will on when there has a voice. ➡ Effective signal output for a low level. The display at its top, will show the sound level (Low, Medium and High), and bottom, a bar that will follow in real time the sound level detected by the microphone will be shown:

The circuit tests will consist of the module Sound Sensor, plus the display 16×2 LCD. The board works with 5V voltage, and the signal pin should be connected preferably to an analog port of Arduino, since the generated signal is variable, and thus we can see the different levels of noise picked up by the microphone. In the middle of the plate, there is a potentiometer for sensitivity adjustment. The connection scheme is very clean, composed of only 3 pins: Vcc, GND, and S (signal).

This board along with the microphone, has a small built-in amplifier (integrated circuit LM393), because only the microphone would not be able to send data for Arduino. Here you will learn how to detect ambient sound and how to handle the signal generated by this module. For the breadboard assembly of the project with Arduino, you can assemble like this.īut if you want to reduce the cost and use it with an ATmega328 microcontroller you can use this circuit diagram. So here we will learn how to interface the Sound Module with Arduino.

The set up is absolutely self-contained and requires no other apparatus. LED by glowing gives the indication that noise is so high. The sound is distinguished as low, medium, and high-level sound on the basis of number. The LCD panel directly displays the information about the sound level in numbers. Decibel Meter using Sound Module & Arduinoĭecibel Meter using Sound Module & Arduino with LCD Display has been designed specifically for detecting the level of sound produced from any source and its intensity as well.
