Unwanted high-frequency sound waves, which are often called “noise pollution,” can make our daily lives very annoying and difficult. Finding ways to block or reduce high-frequency sound waves can make our lives much better, whether it’s the constant hum of machinery, the piercing noise of a building site, or the constant racket from busy city streets. In this blog, we’ll talk about different ways to block out these annoying sounds.

What Is High-Frequency Sound?

High-frequency sound is made up of sound waves that move or vibrate quickly through the air. This gives them a high number of cycles per second, which is recorded in Hertz (Hz). Most of the time, the frequency of these sound waves is between 2,000 Hz and 20,000 Hz. This makes them higher-pitched and often more startling to the human ear than sounds with lower frequencies. To give you an idea of how loud this is, the high limit of human hearing is usually around 20,000 Hz, though this ability tends to get worse as people get older.

There are many things in our surroundings that make high-frequency sound waves. They can come from everyday sounds like the whirring of a blender or the ringing of a phone, but they can also come from more annoying sounds like the screech of car tires, the clamor of industrial machinery, or the piercing noise of building work.

Common sources of high-frequency noise include

Traffic:

Car engines: Whether they run on gasoline or diesel, internal combustion engines in cars make high-frequency noise because of the fast combustion processes that happen inside the engine. When you’re near a busy road, this noise often sounds like a steady whine or hum.

Honking Horns: Car horns make sharp, high-pitched sounds that can be used as warnings or to show anger. When traffic is backed up, these quick noise bursts can be very annoying.

Screaming Tires: Tires make a screaming sound when they lose grip and skid, which can happen when a car stops suddenly or turns quickly. This sound is sharp and high-pitched, and it is both a warning and an annoyance.

Industrial Machinery:

Heavy Machinery: Big industrial machines like bulldozers, excavators, and cranes often have big engines that make a lot of high-pitched sounds. When these tools move, they can also make other sharp sounds, like clanking or grinding.

Power Tools: Tools like angle grinders, jackhammers, and circular saws that spin quickly and powerfully and are used in building, manufacturing, and workshops make high-frequency noise. If you don’t protect your ears, this noise can hurt your hearing.

Equipment in a factory: Different types of machinery, transporters, and manufacturing processes can all add to a constant background of high-frequency noise in an industrial setting.

Construction:

Drilling: On construction sites, drills are often used to make holes in concrete, metal, or other materials. When the drill bit spins quickly and the material is hard, it makes loud, high-frequency noises that can be heard from a long way away.

Sawing: Circular saws, chainsaws, and other tools used in building to cut through wood, metal, and other materials make high-pitched noises as they work.

Heavy Equipment: Cranes, bulldozers, and heavy trucks on building sites make both low-frequency noises from their engines and high-frequency noises from how they move and work.

Household Appliances:

Vacuum Cleaners: As the motor runs and air rushes through the machine, many vacuum cleaners, especially those with strong suction, make high-frequency noise. This noise can be louder or quieter based on how the vacuum is made and how well it works.

Blenders: As they mix and pulverize items, blenders, especially high-speed ones, make high-frequency noise. When breaking ice or blending hard things, the noise level can be especially loud.

Hair dryers: Most hair dryer motors make high-pitched noises when they are in use. When the fan and heat settings are turned up, it can be especially loud.

8 ways to block high frequency sound waves

High-frequency sound waves can keep coming back and bothering us with their loud and sharp sounds. There are, luckily, eight tried-and-true ways to get back to peace and quiet. Here, we’ll show you how to use these effective ways to block high frequency sound waves and make the area quieter.

Filling in the holes and cracks

To soundproof a room or place, the first step is to find and seal any holes or cracks that could let sound in. This step is very important because sound travels quickly through even small holes. Start by taking a close look at your windows, doors, and walls. Look for spaces around door and window frames and cracks in the walls.

Once you know where the problems are, you can shut them off with the right materials. People often use weatherstripping to seal holes around doors and windows. 

It’s usually made of strips of rubber, foam, or silicone that stick to the frame and make a tight seal when the door or window is shut.

You can fill holes in walls with caulk or special sealants made to stop sound from getting through. By fixing these holes and cracks, you’ll make it much harder for high-frequency sound waves to get in.

Curtains that block sound

Soundproof curtains, also called acoustic curtains or drapes, are a good way to absorb sound and keep it from coming into a room. These curtains are made to stop sound waves, so they can be a great addition to your efforts to silence. Most of the time, they are made of heavy materials like fiberglass or many layers of cloth.

High-frequency sound waves can’t travel as far through these materials because they are thick and dense. When silent curtains are hung over windows or doors, they not only keep noise out but also make the room sound better overall. 

Also, they often come with decorative choices that can match the rest of your decor and help block out noise.

Soundproofing panels

Acoustic panels are a flexible and useful way to cut down on high-frequency sound waves in a place. These panels are made to soak up sound, which makes them great for controlling sound waves and echoes. Depending on your needs, you can put acoustic plates on the walls, the ceilings, or both.

They come in different styles, from plain tiles to ones with designs that can make your place look better. Acoustic panels stop sound from bouncing around a room and making echoes by trapping sound energy in their porous or flexible materials. 

This ability to absorb noise makes the surroundings much quieter and more comfortable by reducing the effect of high-frequency noise.

Windows with double panes

Getting double-glazed or even triple-glazed windows is a great way to cut down on noise from outside. These kinds of windows have several layers of glass divided by air gaps or layers of gas to keep the heat in. This design makes noise, especially high-frequency sound waves, harder to get through. When sound waves hit the many layers, they lose energy and are less likely to get to the room inside. 

Double-glazed windows provide better protection against noise and temperature changes, making your home more comfortable and saving you money on energy costs. 

This method is especially helpful if your problem with high-frequency noise comes from the street or other outside sources.

Insulation against noise

Increasing the insulation in your walls and ceilings is a good way to stop high-frequency sounds from getting through. Materials for acoustic soundproofing, like fiberglass and mineral wool, are made to absorb and slow down sound waves. 

Usually, these things are put in the spaces between walls and ceilings when they are being built or fixed up. They work by catching sound energy and stopping it from moving through the building’s structure. Fine glass strands make up fiberglass insulation, which creates a dense and effective sound barrier. 

Mineral wool, which is made from rock or slag, is great at absorbing sound. By adding acoustic insulation, you can make your walls and ceilings much better at blocking sound, making it harder for high-frequency noise to get through.

Doors that stop noise

Standard doors aren’t always good at blocking out high-frequency noise because they aren’t very thick. Soundproof doors, on the other hand, are made with thick materials and locks that stop sound from getting through. 

Most of the time, soundproof doors have a strong core made of wood, metal, or a mix of materials. They might also have more than one layer of soundproofing material inside the door. Also, soundproof doors have special seals around the edges and steps that make an airtight and soundproof barrier when the door is closed.

Installing soundproof doors at key entry places in your home, like bedroom doors or home offices, can make a big difference in how much high-frequency sounds get in.

Solutions for Flooring

If high-frequency noise is coming from the floor above or below you, fixing the floor can help. Soundproof flooring materials, like acoustic underlay or carpets with sound-dampening properties, can help lower the amount of sound that travels through the floor.

Acoustic underlay is a dense, resilient material that goes under floors like hardwood, laminate, or tile. It soaks up noise from impacts and makes it harder for sound to travel between floors. 

High-frequency noise can also be blocked by carpets with sound-dampening properties, especially those with thick padding. These floor options are especially helpful in flats or buildings with more than one floor, where noise from neighbors above or below can be a problem.

Placement of Furniture

Putting heavy, thick furniture against walls in the right way can help block out noise. High-frequency sound waves can be absorbed and blocked by bookshelves, cabinets, chairs, and other large pieces of furniture. 

When sound waves hit these things, they lose energy and don’t bounce around the room as much. It’s important to put furniture along walls in a way that makes a constant barrier against noise. 

Also, think about buying furniture made with sound-absorbing materials, like fabric-covered foam or acoustic walls, for even better sound blocking.

Final Thoughts!

With the right mix of soundproofing methods and materials, it is possible to block high-frequency sound waves. Creating a quieter and more peaceful setting can be done in a number of ways, depending on your situation and budget. Keep in mind that a well-planned soundproofing job can not only make you more comfortable, but it can also increase the value of your home.
