The difference between Peak noise level (L10) and background noise level (L90) is known as:

Correct option is B

In the context of noise pollution, Noise climate refers to the overall characteristics and variations in noise levels over a period, which includes factors such as the difference between peak noise (L10) and background noise (L90). Noise climate takes into account the persistent noise levels (L90) as well as the more transient, peak noise levels (L10), reflecting how a location's noise environment fluctuates. This term is used to describe the general noise conditions in a given area.

Information Booster:

1. L10 represents the peak noise level exceeded for 10% of the time, often reflecting higher intensity, transient noises like traffic or construction.

2. L90 represents the background noise level exceeded for 90% of the time, providing a sense of the quieter or steady noise environment.

3. Noise climate is a broader term that describes the overall noise conditions, including variations in both transient and background noise.

4. The noise climate provides insight into how noise levels change over time, helping in understanding the noise patterns in a region.

5. It is important for urban planning, policy-making, and the assessment of public health risks related to noise pollution.

6. Noise climate plays a key role in determining the acceptability of noise levels in residential, commercial, and industrial areas.

Additional Knowledge:

• Noise environment refers to the total acoustic atmosphere in an area, including all the sounds, but it is not specifically about the difference between L10 and L90.

• Traffic noise index is a different metric used to assess the impact of traffic noise but doesn't directly relate to the difference between peak and background noise levels.

• Sound energy level refers to the energy carried by sound waves and is not directly related to the concept of L10 and L90 measurements.
