According to some research, there could actually be a strong link between lack of muscle gains and noise pollution. Some examples of noise pollution would be things such as; living by an airport, busy street, or apartment dwellers.

Dr. Stephen A. Stansfeld at the University of London has been devoting his research for years on the effects of noise pollution on a person’s health. He found that excessive noise pollution in one person’s life can significantly impact complex motor tasks, social behavior, and sleep.

He also found something that will directly impact bodybuilders gains, by it’s impact on sleep. Noise pollution during sleep increases heart rate, blood pressure, and body movements. It also will effect a person’s performance and mood the next day. The higher cortisol levels during sleep as a result, will lead to a more catabolic state on your muscles. You also will have less energy and focus to do your workouts, which could effect long term muscle gains.
