(1) The document discusses a student project to design an electronic instrument for sound detection and noise reduction using artificial intelligence. (2) The instrument would absorb unwanted noise while allowing required sounds to pass through to reduce the impacts of noise pollution on human and animal health. (3) The proposed design would use a sound detection sensor, amplifier, and AI to instantly detect and filter sounds in a way that makes the instrument useful for noise reduction in populous areas and other noisy environments.

3. Introduction
■ Sound detection:
The discrimination of a sound from backgroundnoise, either by the ear or by an
electronic instrument.
➢ Normal human hearing frequency range: 20 to 20000Hz.
➢ Normal audible range for loudness:0 to 180 dB (>85 dB consideredas damaging).

4. Sound detection Necessary
■ Noise pollution also impacts the health of humans as well as animals.
■ Effects: Blood pressure, heart disease, stress, attention level, memory loss, etc.

5. Our Idea
■ Noise reduction by using an electronic instrument.
■ This electronic instrumentabsorbs the noise and emits the required level of sound
to the ear drum.
■ By using AI in this instrumentdesigning, it is instant to hear.

6. Working
■ Sound detection sensor
■ Amplifier

7. How it is useful?
■ This sound detection i.e., noise reduction instrument is useful as it reduces the
noise.
■ It is used in most populous areas as noise is more.
■ This electronic instrumentcan be used as headphones.

8. Conclusion
■ Artificial intelligence is one of the most vast and developing technological way.
■ Artificial intelligence is mostly based on programming, decision making and problem
solving.
■ In this, sound detection we used it for smart and minimize the size of the electronic
instrument.
■ Sound detection i.e., noise reduction by electronic instrumentis helpful in growing
technology and noisy surroundings.
