Why is Noise Called Unwanted Sound?

Noise can be defined as sound that is unwanted, persistent, and often irritating to the ear. It can have many physical and psychological effects on people, disrupt their concentration, and even lead to hearing loss.

But why is noise called unwanted sound?

Two Categories of Sound

When it comes to understanding why noise is called unwanted sound, it is important to know that sound is broken down into two primary categories: desired sounds, which are desirable and can be enjoyed; and unwanted sounds, which are generally considered annoying.

Desired sounds include the sounds of music and birds singing. Unwanted sounds, such as those of traffic, construction sites, car horns, and loud machinery, are generally considered noise.

Types of Unwanted Sounds

There are many types of noise, and some of them come in different forms:
  • Noise pollution refers to any loud, unnatural, and unwanted sound in a given environment. This type of sound is particularly disruptive in urban areas and can have a negative impact on physical and mental health.
  • Industrial noise is a form of noise pollution created by industries and large-scale manufacturing processes.

  • Environmental noise is caused by everyday activities such as planes flying overhead and people talking or playing music. Environmental noise can be mitigated through the installation of noise barriers or soundproofing materials.
  • Audio interference is any unwanted sound or signal in the audio spectrum.

    It can be caused by electrical equipment, improper grounding, transmitter feedback, or other outside sources.

  • Noise masking occurs when a sound is used to mask or cover up another sound.

    This can be useful when a particular sound needs to be covered up, such as when a person needs to focus on a task or concentrate on a meeting.

Effects of Unwanted Sounds

The effects of noise can be serious and long-term. Long-term exposure to noise can lead to hearing loss, sleep disruption, and other physical and mental health effects. It can also interfere with concentration, disrupt visions, and increase blood pressure. It is important to be aware of the effects of noise, and to take steps to reduce or manage unwanted sound in our daily lives.


Noise is any kind of unwanted sound that is persistent and affects a person’s physical and mental health and wellbeing. Noise pollution, industrial noise, environmental noise, audio interference, and noise masking are all types of noise that can have serious effects on people and their environment. It is important to understand why noise is called unwanted sound, and to take steps to reduce its impacts.
