What are the Best Earplugs for Low Frequency Noise?

Finding solace in silence has become a rare luxury in our fast-paced and often noisy world. Among the myriad of sounds that invade our daily lives, low-frequency noise is particularly insidious. It seeps through walls and windows, usually going unnoticed until it becomes pervasive in our environment. 

This article delves into the nature of low-frequency noise, explores whether earplugs can offer a reprieve, and reviews some of the best earplugs designed to mitigate this type of noise.

What is Low-Frequency Noise?

Low-frequency noise refers to sounds that occur at frequencies below 250 Hz. Common sources include industrial machinery, traffic, air conditioning units, and even natural phenomena like thunder. 

Unlike higher-frequency sounds, low-frequency noise has a longer wavelength, enabling it to travel further distances and penetrate most building materials with ease. This characteristic makes it notoriously challenging to block or reduce effectively.

Do Earplugs Help with Low-Frequency Noise?

Earplugs can indeed help with low-frequency noise, but their effectiveness varies widely based on the design and materials used. Traditional foam earplugs, for instance, are better suited for high-frequency noise reduction. 

However, advancements in earplug technology have led to the development of products that specifically target low-frequency sounds, using materials and designs that help absorb or block these pervasive waves.

When Do I Need Ear Plugs for Low-Frequency Noise?

Studying or Working in Noisy Environments: Earplugs can help reduce distractions when people try to concentrate in environments with a background of low-frequency noise, such as air conditioning units or refrigeration systems.

Attending Concerts or Clubs: While it’s the high frequencies that are typically associated with hearing damage, the physical pressure from bass sounds at concerts or clubs can be uncomfortable or even painful, making low-frequency earplugs beneficial.

Sleeping in Noisy Environments: For light sleepers, low-frequency sounds like the hum of traffic, the drone of a distant factory, or even the sound of a partner’s snoring can disrupt sleep. Earplugs designed to block these frequencies can improve sleep quality.

Traveling on Public Transport: Buses, trains, and subways often operate with a mix of sounds, but the low-frequency vibrations and noises can be particularly tiresome during long journeys.

Working in Construction or Manufacturing: These environments are rife with low-frequency noise from heavy machinery and power tools, which can be distracting and harmful over time.

FAQ on Low-Frequency Ear Plugs

How do you stop low-frequency noise?

Stopping low-frequency noise often requires a combination of methods, including soundproofing spaces with materials that absorb or block these wavelengths and using earplugs specifically designed to reduce low-frequency sounds. 

Adjusting the environment to remove or distance the source of the noise can also be effective.

Are low frequencies bad for hearing?

While low frequencies are less likely to cause hearing damage than high frequencies at the same decibel level, prolonged exposure to loud noise can be harmful. The intensity and duration of exposure determine the risk to hearing health, not necessarily the frequency.

Do earplugs block low frequencies?

Earplugs can block low frequencies, but their effectiveness depends on the design and materials. Earplugs tailored for low-frequency noise reduction, such as those reviewed above, are more effective than standard foam earplugs.

Why do earplugs not block bass?

Bass sounds are low-frequency waves that can travel further and penetrate materials more easily than higher-frequency sounds. Earplugs, especially foam ones, may not completely block bass because they’re less effective against these longer wavelengths. However, specialized earplugs use different materials and designs to tackle low-frequency sounds, including bass, better.


The quest for quiet in a noisy world is ongoing, but with the right earplugs, it’s possible to find a respite from low-frequency noise. Whether you’re looking to enhance your focus, protect your hearing, or simply enjoy a moment of silence, the earplugs reviewed here offer a range of solutions tailored to different needs and preferences. 

While no earplug can completely eliminate low-frequency noise, these options represent the best in class for reducing its impact on your life.
