12+ Ways On How To Block Out Low Frequency Noise : 100% Working

Muffling low-frequency noise is the most challenging task while soundproofing your house. Low-frequency sound waves can travel longer distances and easily enter your house through corridors, walls, or ceilings. 

Some examples of low-frequency noise include the sound coming from traffic or industrial sites. These sound waves are difficult to avoid and can cause problems concentrating on your work. If you have babies or older adults at home, then consistent hearing of loud noise can make them difficult to sleep. 

It can even lead to various physical and mental health problems. So you need to block the low-frequency sound waves by adding mass and soundproofing materials.

The article discusses how to block Out low frequency noise. So, keep reading this article to learn about some excellent ways to reduce low-frequency noise.

What Are Low-Frequency Sound Waves?

Sound travels in the form of waves. It can travel in air, water as well as in air. It causes vibration in air particles or solid medium and thus travels from one place to another. Sound is usually measured in the unit of frequency. So the frequency of sound will indicate how many times it has repeated and reached your ears.

Low-frequency sound waves usually have a pitch between 10 to 200 HZ, while humans can perceive sound from 20 to 20,000 HZ. That’s why it is hard to hear low-frequency noise.

You may not hear the noise clearly, but you can feel these annoying waves. 

Boilers, fans, traffic, or generators usually produce these sound waves. So, if you cannot sleep peacefully because of low-frequency noise, there is a higher chance that the sound can come from your neighbors or nearby site.

 Sound waves generally use energy while traveling. But when they vibrate the air particles while traveling, the energy is usually lost and thus cannot travel greater distances. It is mainly true in high-frequency sound waves.

But low-frequency sound waves don’t use much energy during traveling. Hence they travel greater distances. 

The low-frequency noise can readily travel through walls, floors, ceilings, and corridors. So, you must know various ways of blocking low-frequency noise to live in a peaceful atmosphere.

We recommend you identify the source from where the low-frequency sound is coming and then address it instantly before you feel its adverse effect.

Effects Of Low-Frequency Noise

Low-frequency noise is frustrating and irritating when you want to concentrate on your office work or have a sound sleep after a tiring day. You need to address this noise immediately; otherwise, it will create several mental and physical health issues.

An article published in the National Library of Medicine states that ran University did an experiment with 90 individuals, of whom 54 were male and 36 females. These individuals were allowed to do various tasks under a sound frequency of 50-70 HZ.

The results concluded that the individuals could not focus on work because of the low-frequency noise. They were getting weak mentally because of this noise frequency.

Remember, consistent hearing of low-frequency noise can cause health problems like cardiovascular diseases, high blood pressure, insomnia, and many more. So, address the problem immediately and block the low-frequency noise.
