Do Bone Conduction Headphones Leak Sound and Best Headphones with Less Sound Leakage
Feb 08,2023 | David
Bone conduction headphones are becoming more and more popular. While running and riding, you can see people wearing a new type of music-listening device around their auricle, which is bone conduction headphones. Bone conduction headphones are a new type of earphone based on bone conduction technology. It does not need to transmit sound through the air in the ear canal like traditional earphones but transmits sound through the skull. Bone conduction earphones have a lot of advantages, but they also have some disadvantages, such as sound leakage.
Do bone conduction headphones leak sound?
Bone conduction headphones will leak sound, but now some mature brands have found a solution to the problem of sound leakage, such as wissonly and Aftershokz have done a good job in reducing sound leakage.
The sound leakage problem of bone conduction headphones is mainly due to the fact that they convert sound into mechanical vibration through the sound unit, and vibrate the bone to transmit sound. When the headphone is working, the shell of the headphone will be vibrated together by the sound unit, and the shell will vibrate the surrounding air, so sound leakage will occur. In other words, the shell of the bone conduction headphone becomes the “amplified speaker” of the headphone, spreading the sound to the surroundings.
From the principle of the sound leakage phenomenon, we can easily see that all bone conduction headphones have sound leakage problems. Those headphones that claim to have no sound leakage at all are basically fake.
It’s just that some bone conduction headphones may have made more efforts to reduce sound leakage. For example, some headphones use anti-phase sound waves to offset the sound waves of sound leakage, or through the integrated design of the body without holes, reduce the air vibration caused by the vibration unit, thereby reducing sound leakage. There are also some brands that optimize the structural design and increase the shock absorption function of the body to reduce sound leakage. It should be said that with the efforts of the entire industry, the sound leakage of bone conduction headphones has also been greatly improved.
Although bone conduction headphones have the problem of sound leakage, it has to be said that they have several outstanding advantages
Safer: Wear them without blocking your ears, which allows you to maintain awareness of your surroundings and make outdoor sports safer;
Healthier: They use bones to transmit sound and do not need to use the eardrum, which avoids damage to the eardrum and can protect hearing well;
More hygienic: bone conduction headphones do not need to be worn in the ear, even if worn for a long time, they can keep the ear canal clean and avoid the growth of bacteria;
More comfortable: They are very light, there is no feeling of weight when wearing them, and the wearing comfort is very high.
The advantages and disadvantages of bone conduction headphone are determined by its working principle.
How bone conduction headphones work？
How can you hear the sound without putting headphones in your ears? Many people have such questions. To understand how bone conduction headphones work, let’s first understand how humans recognize the sound.
You may think that humans hear sounds with their eardrums, but this is not accurate. The sound we normally hear is vibrations in the air entering the ear and hitting the eardrum causing it to vibrate. Humans perceive the vibration of the eardrum through the cochlea located deep in the ear and transmit this information in the form of sound to the brain to perceive sound. In other words, humans perceive sound through the cochlea. From this perspective, humans hear sound through the cochlea.
Bone conduction headphones make good use of the above-mentioned mechanism of the cochlea to perceive sound. They apply vibration directly to the facial bones, and the facial bones transmit the vibrations to the cochlea, where the sound is perceived by the cochlea.
We can compare the difference between bone conduction and traditional sound transmission paths to understand more deeply how bone conduction headphones work.
Bone conduction path: sound wave,cranium,bone labyrinth,inner ear lymph,Spiral organ,auditory nerve,cerebral cortex auditory center.
Traditional sound transmission path (i.e. air conduction path): sound wave,auricle,external auditory canal,eardrum,auditory ossicles,vestibular window,internal and external lymphatics,spiral organs,auditory nerve,cerebral cortex auditory center.
We can see that the sound transmission process of bone conduction headphones does not need to pass through the eardrum, its sound transmission path is shorter, and it will not damage the eardrum.
The following are recommendations for several excellent bone conduction headphones. Some of these headphones have good sound quality and sound leak reduction, and some are low-cost entry-level products.
