Single-microphone hearing aids
The working mechanism of single-microphone hearing aids is relatively intuitive. It is like a loyal guard who listens to all directions, receiving sound signals from the surrounding 360-degree space in all directions. No matter where the sound comes from, it captures it equally, and then amplifies these sounds uniformly, so that the originally weak sound waves can be enhanced and then transmitted to your ears.
This type hearing aid has a relatively simple structure, without too many complex structures and technical integrations. In addition, its small and light appearance design makes you feel almost no extra burden and can be easily adapted. It is mostly used for deep-canal invisible and ultra-invisible hearing aids, with a mini and compact appearance that almost disappears in the ear canal.
Dual-microphone hearing aids
Dual-microphone hearing aids have achieved significant advancement in hearing assistance functions. Its working principle is like a sophisticated sound navigation system, relying on the tacit cooperation of two microphones. One of the microphones is like a keen outpost, focusing on collecting sound signals directly in front, while the other microphone is like an all-round scout, fully monitoring the sounds of the surrounding environment. Through advanced algorithms, the sound information received by the two microphones is deeply analyzed, and the key data such as the time difference and intensity difference between the sound and the two are accurately calculated, so as to accurately determine the source direction of the sound. Based on this, the hearing aid can amplify the target sound in front while cleverly reducing the background noise interference from the back and both sides, greatly improving the signal-to-noise ratio. This is like opening up a clear sound channel for you in the noisy world, so that you can still accurately capture the voice of the person you are talking to in a noisy environment, such as a bustling shopping mall or a crowded gathering place, and achieve barrier-free communication.
This type of hearing aid is highly consistent with the needs of people with moderate to severe hearing loss. If you find it difficult to listen in a moderately noisy environment, and the audiogram shows a more prominent feature of hearing loss in the mid-frequency band, then the dual-microphone hearing aid is very likely to be your right-hand man. For you who have a very rich life and more social activities, the dual-microphone hearing aid is undoubtedly your right-hand man who can shuttle freely in multiple social scenes and daily life, helping you seamlessly integrate into various environments and significantly improve the quality of life and social experience.
Three-microphone hearing aids
The working principle of three-microphone hearing aids is like building an all-round, multi-dimensional sound detection matrix. Among them, two microphones are carefully arranged on the same horizontal plane. They are like pioneers of sound detection in the horizontal direction. They work closely together to achieve extremely accurate positioning of the sound source in the horizontal direction by ultra-precisely calculating and analyzing the time difference and phase difference between the sound and the two. Its high accuracy is like drawing a clear horizontal sound map for you. The third microphone is like a sound capture elf in the vertical direction. It is usually cleverly placed in the key position of the hearing aid and is responsible for the collection and processing of sound information in the vertical direction. In this way, the three microphones cooperate with each other to successfully build a three-dimensional sound positioning system, as if creating a 3D surround sound sound perception space for you. It is precisely because of this excellent working principle that three-microphone hearing aids can show extraordinary noise resistance when facing extremely complex and harsh noise environments, such as busy and noisy streets, or near factory workshops with roaring machines and deafening noises. It can be like an intelligent noise filter, which can suppress the interference of noise to the maximum extent, accurately extract the target sound, and amplify it clearly, making you feel as if you are in a quiet oasis of sound. At the same time, it also has a powerful personalized hearing adaptation ability, which can make subtle adjustments to the sounds of different frequency bands according to your unique hearing chart, and tailor the most optimized hearing compensation plan for you.
In the long journey of selecting hearing aids, the number of microphones is only “one” of many key considerations. We also need to comprehensively consider many factors such as our degree of hearing loss, the type of environment in which we engage in daily activities, our age, and our personal economic situation. Therefore, it is strongly recommended that you conduct a comprehensive and in-depth hearing test and comprehensive evaluation under the careful guidance of a professional audiologist, so as to accurately choose the hearing aid solution that best suits you. Let the hearing aid no longer be just a cold medical device, but become the most intimate hearing partner in your life, accompanying you to embark on a wonderful journey of appreciating the colorful world of sound in the world.
