Noise in English: Understanding and Expressing Sound Pollution，In todays fast-paced world, noise pollution has become an increasingly pressing issue. From bustling cities to quiet residential areas, understanding the English terminology related to noise is crucial for effective communication and addressing this environmental concern. In this article, well delve into the various ways to describe noise in English and explore the science behind it.
1. Basic Terminology
To start, lets familiarize ourselves with some fundamental terms:
- Sound: A vibration that travels through the air, water, or other medium as a wave.

- Loud: 85-90 dB (Busy street or industrial area)
- Very loud: Over 90 dB (Potential hearing damage risk)
