Why choose open-ear headphone? We will show from the following points:

(1) Hearing loss caused by long-term use of traditional earphones

The data released by World Health Organization (WHO) shows that, there are about 1.1 billion young people between the ages of 12 and 35 are at risk of irreversible hearing loss in the world, Now, about half of the world's young people listen to music at volume above safe levels on devices such as mobile phones. Excessive volume on personal audio devices such as use phone to listen to music is an important cause of hearing loss risk. 

Wearing a traditional headset while listening exposure to loud music causes hair and nerve cells that give hearing to become tired, irreversible damage will be caused in the long run.

What are the dangers of listening to music with traditional headphones for too long?

1. Using traditional earphones for a long time is likely to cause a decrease in auditory nerve sensitivity, cause tinnitus, mild hearing loss, etc. Deafness can occur in severe cases

In a survey of 3,826 college students, it was found that the headset utilization rate was as high as 99.8% among the students, and the number of students who had noise-induced hearing loss was more than 1,000, accounting for nearly 30%.

2. Wearing headphones for a long period of time can expose the cochlea to high-frequency stimulation, which can increase the risk of acoustic neuroma.

3. Wearing headphones for a long period of time can have a lasting impact on the cochlea. When exposed to high decibel sounds for a long time, the inner ear can suffer direct damage.

4. Some students will also have the phenomenon of difficulty in concentration, decreasing sensitivity of thinking and reaction.

5. It may also affect traffic safety for those who ride with headphones on.

(2) Casualties caused by the use of traditional headphones

Now with the popularity of mobile phones, people begin to rely too much on a cell phone, work, rest, never leave. When crossing the street or riding, they wear headphones to listen to music, and are indifferent to the sound of cars behind them. Due to some uncontrollable factors, too late braking and pedestrian avoidance caused a traffic accident, and this incident of casualties has risen rapidly in recent years.

(3) Restrictions on the use of traditional headphones in various countries

In the United States, 14 states ban cell phone use while driving. In the UK, police can be fined if they think a driver is distracted. Some countries, including China, France, Belgium, Spain, New Zealand, Australia and Russia have also enacted laws banning the use of mobile phones or wearing headphones to listen to music while driving

Current market conditions and popularity of the new open earphones

It is precisely because of the various drawbacks of traditional headphones that engineers around the world have begun to study new technologies to solve these drawbacks. ALOVA Company has also invested a lot of research and development funds, go hand in hand with international giants, made significant progress in bone conduction and directional audio technology, and developed a number of products.

We can see from Google’s search data that the core keyword data report from 2016 to 2020: the search volume of open Bluetooth headsets has exploded, and the global sales of open Bluetooth headsets have also exceeded 100 million.

What are the usage characteristics and related product models of ALOVA openear headphone?

(4) Wearing of ALOVA openear headphones

The wearing of openear headphones don't require to plug earphones into the ears, nor to wrap the ears´╝îdesigned entirely with ergonomics. ALOVA's openear headphones are made of very high-end materials. The earphones can be twisted 360 degrees. It only weighs more than ten grams. You can't feel the earphones wearing them at all.

The wearing of openear headphones don't require to plug earphones into the ears, nor to wrap the ears. So when the warning sound comes from outside, it will react immediately, and it will not cause hearing loss.

(5) The spread type and working principle of ALOVA openear headphones

Since it is comfortable to wear, many users will ask what is the working principle of these openear headphones? ALOVA currently has two types of openear headphones for communication technology.

1. Bone conduction technology spread
Bone conduction technology is actually because of bone transmission

It starts with how we heard the voice. Under normal circumstances, sound waves are introduced into the inner ear through air conduction and bone conduction, and then the inner and outer lymph fluids of the inner ear are vibrated. The spiral device completes the sensory process, and then the nerve nerve impulses are generated and presented to the hearing center and the brain. After a comprehensive analysis of the cortex, the voice is finally "heard". Maybe we are more or less perceptually aware of air conduction (the path is sonic-auricle-external auditory meatus-tympanic membrane-hammer bone-incus-stapes-vestibular window-external, endolymphatic-spiral device-auditory nerve-auditory center) but for for bone conduction, we don’t know it at all. Maybe you could got it via an example: cover your ears with your hands, talk to yourself, no matter how small the sound, we can hear what we say, this is the result of bone conduction.

We could understand it more intuitively through the following picture

2. Directional audio technology spread
Directional audio technology is a groundbreaking audio solution that provides an effective way of sound transmission without the need to use a large speaker array, and can also project sound highly directionally into a specific area, creating an accurate, quiet, Independent audio space that does not interfere with the surrounding environment

Next, we use a picture to understand the essential difference between traditional audio and directional audio

The development of directional sound technology can basically evolve from the development of super directional speakers. Super-directional loudspeaker (super-directional loudspeaker), which can produce high directional sound, is a new generation of speaker system. The energy of the sound waves emitted by the system is concentrated, and the sound only propagates in the specified direction, and the sound intensity does not significantly attenuate with the distance during the propagation process, so that the sound propagation distance is greatly improved. In addition, it is also possible to form a virtual sound source effect through reflection. The United States, Germany and Japan have already begun to apply this technology, and Singapore and the Chinese Academy of Sciences are also conducting research in this area.

The super-directional speaker adopts advanced digital signal processing technology to load audible sound signals onto the ultrasonic waves and emit them. When two columns of ultrasonic waves with different frequencies propagate in the same direction in the air, the two columns of ultrasonic waves will interact due to nonlinear effects. Function and self-demodulation to generate their sum frequency signal and difference frequency signal. If the difference frequency sound wave is in the audible sound domain, audible sound is generated. Due to the high directivity of ultrasound propagation, the audible sound waves also have directivity.

The new generation of super directional speakers have five characteristics of super directional, low distortion, super long distance, virtual sound source and ultra-thin characteristics. It has a narrow beam angle to avoid mutual interference of different sound sources, and can reduce distortion through preprocessing algorithms to meet the needs of ordinary speech and music. In addition, the sound intensity no longer attenuates with the distance sphere, increasing the propagation distance, and the object can also produce the effect of sounding through the reflection of the object.
