The primary goal of noise control is to reduce noise to acceptable levels, rather than eliminating it completely.

Noise masking is not a common method of noise control, as it involves adding additional noise to cover up unwanted noise.

Soundproofing involves using materials and techniques to block sound waves from passing through a barrier.

Concrete is a dense material that is effective at blocking sound waves.

Vibration isolation involves using materials and techniques to reduce the transmission of vibration from one object to another.

Rubber is a flexible material that is effective at absorbing vibration.

Active noise cancellation involves using a secondary sound wave to cancel out unwanted noise.

Headphones are an example of an active noise cancellation device, as they use a secondary sound wave to cancel out unwanted noise.

Noise masking involves adding additional noise to cover up unwanted noise.

White noise machines are an example of a noise masking device, as they produce a constant, broadband noise to cover up unwanted noise.

Soundproofing involves blocking unwanted noise from passing through a barrier, while noise masking involves adding additional noise to cover up unwanted noise.

Noise control is commonly applied in industrial settings, residential areas, and transportation vehicles to reduce unwanted noise.

Excessive noise exposure can lead to a variety of health effects, including hearing loss, tinnitus, sleep disturbance, and cardiovascular problems.

There are a variety of legal requirements for noise control, including OSHA regulations for workplace noise exposure, EPA regulations for noise pollution, and local noise ordinances.

There are a variety of challenges in implementing noise control measures, including cost, technical feasibility, and public acceptance.
