Imagine trying to enjoy a peaceful evening, only to be bombarded by the relentless honking of horns, the blare of loudspeakers, and the rumble of construction. That, my friends, is sound pollution in a nutshell. In Bangladesh, especially in bustling cities like Dhaka, sound pollution is more than just an annoyance; it's a serious environmental and health hazard. So, let's dive into understanding what sound pollution is, its causes, effects, and what we can do about it.
What is Sound Pollution?
Sound pollution, also known as noise pollution, is unwanted or excessive sound that can have adverse effects on human health, wildlife, and environmental quality. Think of it like this: your favorite song played at a reasonable volume is music to your ears, but the same song blasted at full volume in the middle of the night? That's sound pollution!
Understanding the Decibel Scale
Sound is measured in decibels (dB). A whisper is around 30 dB, normal conversation is about 60 dB, and a rock concert can reach 120 dB. Prolonged exposure to sounds above 85 dB can cause hearing damage. In Bangladesh, permissible sound levels vary by area, but are often exceeded, especially in urban areas.
Table 1: Common Sound Levels and Their Effects
| Sound Source | Decibel Level (dB) | Potential Effects |
|---|---|---|
| Whisper | 30 | Generally harmless |
| Normal Conversation | 60 | Comfortable, no risk of hearing damage |
| City Traffic | 85 | Risk of hearing damage with prolonged exposure |
| Rock Concert | 120 | Immediate risk of hearing damage |
| Jet Engine at Takeoff | 140 | Painful, immediate and permanent hearing damage risk |
