Why does construction noise sound louder at night?
The absence or reduction of background noise from traffic, work and other daytime activities may cause construction noise to sound louder at night. An example of this effect is the volume on your car radio. When you get on the freeway, you have to turn the volume up because the traffic noise masks the sound of the radio. When you get off the freeway and stop at a traffic light , the same volume level is much too loud and you have to turn it down. The same principle applies to how people perceive nighttime construction noise.
