Step 1: Understand noise pollution and its effects.
Noise pollution is unwanted or harmful sound that can adversely affect human health and environmental quality. Prolonged exposure to high noise levels can cause hearing loss, stress, sleep disturbances, and other health problems.
Step 2: Role of EPA standards.
The Environmental Protection Agency (EPA) sets permissible noise limits to protect public health and welfare. These limits vary by the type of area (residential, commercial, industrial) and the time of day (daytime or nighttime).
Step 3: Noise limits in residential areas during daytime.
Residential areas require stricter noise control because people spend more time at home and need quieter environments. The EPA recommends that the noise level in residential zones should not exceed \(\mathbf{45 \text{ dB}}\) during the daytime. This limit helps in minimizing adverse health effects and maintaining a peaceful living environment.
Step 4: Comparison with other zones.
Commercial areas typically have a higher permissible limit (around 65 dB) due to increased activity.
Industrial zones may allow up to 75 dB or more due to the nature of activities.
Step 5: Conclusion
Hence, the permissible noise pollution limit in residential areas during daytime, as per EPA standards, is \(\boxed{45 \text{ dB}}\).
