What To Know
- Unlike traditional headphones that rest on or in the ears, bone conduction headphones sit just outside the ear canal, sending vibrations through the bones to the inner ear.
- Traditional noise cancellation headphones use microphones to detect external noise and then emit a sound wave that is equal in amplitude but opposite in phase to the incoming noise, effectively canceling it out.
- The headphones’ design, which includes a tight seal around the ear canal and a snug fit on the head, helps to reduce the amount of noise that reaches the inner ear.
Bone conduction headphones have become increasingly popular in recent years due to their unique design and ability to deliver sound through the bones of the skull. Unlike traditional headphones that rest on or in the ears, bone conduction headphones sit just outside the ear canal, sending vibrations through the bones to the inner ear. This design has several advantages, including improved comfort, reduced risk of ear infections, and the ability to stay aware of your surroundings while listening to music or podcasts.
One of the most common questions about bone conduction headphones is whether or not they have noise cancellation. The answer is yes, but it’s important to understand how bone conduction noise cancellation works and its limitations.
How Does Bone Conduction Noise Cancellation Work?
Traditional noise cancellation headphones use microphones to detect external noise and then emit a sound wave that is equal in amplitude but opposite in phase to the incoming noise, effectively canceling it out. Bone conduction headphones, on the other hand, use a different approach called passive noise cancellation.
Passive noise cancellation works by physically blocking out external noise. The headphones’ design, which includes a tight seal around the ear canal and a snug fit on the head, helps to reduce the amount of noise that reaches the inner ear. This type of noise cancellation is less effective than active noise cancellation, but it is still beneficial in reducing background noise.
Limitations of Bone Conduction Noise Cancellation
While bone conduction headphones offer some noise cancellation, it’s important to note that it is not as effective as active noise cancellation. Active noise cancellation uses microphones and digital signal processing to create a more precise and effective cancellation of external noise. Bone conduction headphones, on the other hand, rely on passive noise cancellation, which is less effective at blocking out high-frequency noise.
Benefits of Bone Conduction Headphones
Despite the limitations of their noise cancellation capabilities, bone conduction headphones offer several benefits, including:
- Improved Comfort: Bone conduction headphones are more comfortable to wear than traditional headphones, as they do not rest on or in the ears. This makes them ideal for extended listening sessions or for people who are sensitive to ear pain.
- Reduced Risk of Ear Infections: Traditional headphones can trap moisture in the ear canal, which can lead to ear infections. Bone conduction headphones do not enter the ear canal, so they reduce the risk of these infections.
- Awareness of Surroundings: Bone conduction headphones allow you to stay aware of your surroundings while listening to music or podcasts. This is important for safety when walking or biking, or for people who need to be able to hear important announcements or conversations.
- Open-Ear Design: Bone conduction headphones have an open-ear design, which allows you to hear the world around you while listening to music. This is ideal for people who want to enjoy music without being completely isolated from their surroundings.
Drawbacks of Bone Conduction Headphones
Along with their benefits, bone conduction headphones also have some drawbacks, including:
- Limited Sound Quality: Bone conduction headphones do not produce the same sound quality as traditional headphones. The sound can be tinny or muffled, and it may be difficult to hear certain frequencies.
- Less Effective Noise Cancellation: As mentioned above, bone conduction headphones offer less effective noise cancellation than active noise cancellation headphones.
- Can Be Uncomfortable for Some People: While bone conduction headphones are generally comfortable, some people may find them uncomfortable to wear for extended periods of time.
Summary
Bone conduction headphones offer a unique alternative to traditional headphones, with benefits such as improved comfort, reduced risk of ear infections, and awareness of surroundings. However, it’s important to understand the limitations of their noise cancellation capabilities and to choose headphones that meet your specific needs.
