Noise Pollution

Is that Noise just a Bump in the Night?


A sound/noise is created when the molecules in the air bump into one another, which in turn bump into the next molecules, and continues traveling until the energy runs out. When it reaches any ear, it is translated into a vibration what is recognized as a sound/noise. (

Our evolutionary response to unfamiliar noise can trigger a potent stressful anxiety. Our bodies boost the heart rate, breathe less deeply, and release fight-or-flight hormones. Even wildlife gets stressed out by noise. (

Those familiar noises can become overwhelming.

Human's sensitivity to sound increases at times of stress, making previously unheard background noises or a familiar sound that has been modified to sound strange, suddenly very prominent. (   

Houses, whether new or old, make plenty of noise, creaking door, the strange rattling in the walls, and the squeaking stairs. You might not notice it during the hustle and bustle of the typical day, but when things calm down at night, all those noises come out. 

Clicking, Knocking, and Clanking”, no, that's not the sound of chains rattling in the attic. If it's cold weather, these sounds may be from turning on the heater. Those dust work vents are expanding and contracting. The noise could be coming from your roof during the hottest days of the summer, when the rays of the sun beat down on the shingles; they’re contracting and expanding too. Whistling in the Dark is not a happy ghost; it's a very unhappy furnace or air conditioning filter when the filter is dirty. 

Scratch, Scratch, Scratching” may sound like your walls are haunted, in reality it's the tiny fingernails or teeth of a rodent or wild critter in your house turning your insulation into a comfy bed.

Bubble, Bubble, Toil and Trouble” goes that popping sound, it isn't the wicked witch. Just your water heater, where sediment has settled at the bottom of the tank, then popped and bubbled as the water heats. Then comes the “Bang—Bang—Bang” of that wild hammering you hear of air pressure in the water pipes.

Houses are made up of a combination of wood, glass, concrete and other materials that contract and expand at different rates and other strange sounds that might surprise you when you least expect it. If you have a noise that persists and you're getting concerned, it never hurts to call in the pros and get an opinion for your own peace of mind. Shannon Dauphin Lee

If your home (a bastion of peace, quiet and calm) is in an area with pervasive noise pollution, your neighborhood could be dangerous to your health. Conditions brought on by noise pollution include insomnia, hearing loss and heart health issues. Understanding sound frequencies and identifying the causes can help you survive. We have become accustom to noises with great cost to our mental health. 

· Police sirens: 118 db; 

· AC unit: 60 db; 

· Heavy street traffic: 70 db; 

· The Ordinary conversation 60 dB: compared to a 30 dB: Soft whisper. 

When you go looking for a new home, be aware of venues where major concerts and events are held and loudspeakers are used; construction sites; industrial sites; dogs with high-pitched barks; and other loud at-home machinery that are in continual use.

Knowing the sounds of your neighborhood will help you maintain that precious “peace of mind” and a happy ‘Spirit’ in your home.
