Question

What is the difference between noise and music? Can music become noise sometimes?

Answer 1

Hint – In this question use the basic definitions of the noise and music to differentiate between these two separately. A music provides sensation to hearing and is pleasant to ears whereas a noise is unpleasant and is generally regarded as disturbance or unwanted. This will help to approach the problem.

Complete step-by-step answer:
The difference between the music and noise is given below in the following table:

S.No	Music	Noise
1.	Any sound that pleases our ears is termed as music.	Any unwanted sound that does not please our ears is called noise.
2.	It is produced by musical instruments such as sitar, guitar, violin, keyboard etc.	It is produced by heavy duty trucks, railway engines horns, aircraft, car, faulty loudspeaker etc.
3.	Music has frequency and wavelength that are harmonious.	While noise has irregular waveform and wavelength and has low frequencies.
4.	Music has a very soothing and pleasant effect.	While noise has created obstruction and confusion between the two people when they are taking or communicating with each other.

Noise pollution:
It is also known as sound pollution or environmental noise. It is the measure of the degree of the extent that produces the noise for example noise caused by aircrafts, machines transport etc.
Some of the noises are very harmful for human beings as well as for the animals even cause permanent hearing loss.
Noise is measured in decibel often denoted by (dB).
Normal conservation tone is about 60 dB, everything greater than 85 dB will be harmful to us.
Some of the measures to reduce noise pollution in our residential area are given as:
Stay away from Noisy area
Noise producing industries, airports, and vehicles should be far from residential areas as it is very dangerous for infants and senior citizens.
Follow the Limits of Noise level
Community law should check use of loudspeakers, outdoor parties as well as political public announcements.
Control Noise level near sensitive areas
There should be control on noise level (Silent zones) near schools, hospitals. Place noise limits boards near sensitive areas.
Go Green by planting trees
We can plant more trees as they are good noise absorbents. According to studies it can reduce noise by 5 to 10 decibels (dB) around them.
Use Proper Lubrication and Better maintenance
We can use proper lubrication as well as better maintenance of machines to reduce noise pollution and improve efficiency. It reduces friction between movable parts and helps to reduce noise.
Some other measures are urban planning, better designing of roads, applying limits on vehicles speed, noise barriers etc.
Hence music can become noise when played at higher volumes.
So we have to play music at appropriate volume so that it can please us.
So this is the required answer.

Note – In general the sound waves that we hear have both fluctuations of pitch and frequency and that what differentiate sound from two different objects. For a normal healthy human being the pitch starting at Hz or above can easily be listened to. Moreover human ears are sensitive to frequency range between 500 to 4000 Hz.
