How To Block Ultrasonic Sound Waves – Know it All!

Maybe you’re concerned about the irritating buzzing noises in your home. What’s the harm? These are high-pitched ultrasonic sound waves emitted by various electronic devices around us.

Ultrasonic waves are louder than the human audible range of 20 Hz to 20 kHz, and we can’t hear them. Even if they are not heard, they can cause serious hearing damage if heard frequently and exceed the sound pressure level of 70dB. 

However, there is nothing to worry about when this article discusses how to block ultrasonic sound waves. Let’s give it a roll!

What is Ultrasound?

Ultrasound is the high-pitched sound frequency that exceeds the human audibility range.

Humans can typically only hear frequencies ranging from 20 hertz (Hz) to 20000 hertz (Hz). Any frequency outside of this range is inaudible to the human ear. Animals, on the other hand, can hear ultrasound and many animals, such as bats, use ultrasound waves up to 50000 Hz to communicate.

Ultrasound waves, on the other hand, begin at 20000hz and can reach several gigahertz. Ultrasound waves are mostly used in medical equipment to diagnose various problems in the human body.

How To Block Ultrasonic Sound Waves?

Ultrasonic waves are distinct from the regular sound. We can distinguish between low, mid, and high frequencies in our hearing range. Unfit humans can’t hear the high-frequency of 8kHz to 20kHz. 

The ultrasonic frequency exceeds 20kHz, so we can’t hear it. But they can create tremendous pressure in the air. With enough sound pressure, a human can be killed. So, here are some ways to block ultrasonic sound waves.

Try Using Some Earplugs

It is not always like you have to renovate the house to block the ultrasonic sound. Most of the time, it can breach the blockades you create as the pressure of ultrasonic waves is way greater than regular sound waves. So, you can try on some earplugs when you are around machinery or sources that create ultrasonic sound waves.

Remodel Your Home

This is a tip to block ultrasonic sound waves if you move to a new house. To block the ultrasonic waves and high-frequency sound waves from entering your home, you can use some acoustic padding or a thick layer of spray foam on the walls. 

However, the acoustic soundproof sheet can cost you more money than the spray foam. But they are a good solution to keep the unwanted noise away and keep you healthy. 

Keep Away From Machinery

Mostly, the source of high frequency or ultrasound waves is the machinery in your house. Mostly, the refrigerator creates a buzzing noise because of its compressor. 

The compressor in machines like air conditioning and refrigerators creates a tremendous amount of noise, which can kill a human being if not compressed. 

As a result, when compressed, they can produce high-frequency waves that are not audible to us but are still harmful. So, keep such machines in places far from your bedroom.

Use of Thick Curtains

This may be the mighty solution to blocking ultrasonic waves, but it works. You can use thick curtains, mostly soundproof ones, to block the sound waves. You can find special soundproof curtains online to hang on the doors and windows. They can help you initially block the ultrasound waves.

Frequently Asked Questions

How Do You Detect Ultrasonic Waves?

Ultrasonic sound waves are measured mostly with radiometers. This meter is one-of-a-kind in that it determines ultrasonic waves using a small mirror and a fan.

The sound waves are passed through a thin, lighted wire by the mica fan in the machine known as the mica fan. A mirror then picks up the movement of the wire caused by sound pressure, and the frequency of the ultrasound is found.

What Are The Uses of Ultrasound?

There are many uses of ultrasound waves. But, mostly, it is used in hospitals and labs to determine several diseases in humans. The most common use of ultrasonic waves is to get a detailed view of the unborn baby. Also, it is used for:

  • gallbladder disease.
  • Screen blood flow.
  • Examine the breast tumor.
  • To check the thyroid gland.
  • Determine prostate issues.
  • Assess synovitis.
  • Evaluate bone disease.

Final Words

Because ultrasound waves are the highest sound frequencies, you cannot completely block them. It isn’t necessary to block them if it is in medical use as experts say. However, for your safety and comfort, these methods to block ultrasonic sound waves can be extremely beneficial. 

However, in the case of blocking ultrasonic waves, the adage “prevention is better than cure” applies. So, if you’re thinking about buying a new house or building one, make sure it’s completely from the sources of high-frequency and ultrasonic sound waves.
