On the occasion of the Mid Autumn Festival, the editor will take you back to listen to the wonderful performance of the doctor at the 2018 Entrepreneurship Hero Conference. CCTV Finance Channel's "Entrepreneurial Heroes Gathering" Issue 2018-11-30 Highlights: Noise problems abound, how ultrasonic directional technology isolates noise pollution

As the elders in the family grow older, it is inevitable that they may have weak hearing. If the weak hearing elderly feel that they can hear clearly, then the sound of the TV may fill every corner of the entire room. When we are in a commercial street or a pedestrian street, the big loudspeakers sold at the entrance of shops are deafening and noisy, making us feel trapped in the ocean of sound pollution

Due to its inherent characteristics, sound spreads like ripples and is difficult to control. However, entrepreneur Yang Jianfeng can make sound like a beam of light - steady! Go ahead! Spread it! Broadcast!

Some people may say, 'Wearing headphones can also allow you to enjoy the sound alone.' However, domestic and foreign scientists have confirmed that long-term use of headphones can cause irreversible damage to hearing. Therefore, how to enjoy the auditory feast in a healthy way is the signature skill of the 'Listening Doctor'. The trick is to focus on the designated sound area and hear the sound outside the area - instant attenuation! Just like the beam of a flashlight.

Core Skill 2: Frequency Conversion
For the hearing-impaired, traditional hearing aids simply amplify volume. In contrast, "Doctor of Listening" adjusts inaudible frequencies to a range detectable by the user without increasing volume, enabling clear hearing without causing ear damage.

Core Skill 3: Surround Sound
Similar to 3D visual technology, "Doctor of Listening" leverages the natural hearing differences between human ears. Without requiring any wearable devices, it uses minimal speakers to create an immersive 3D surround sound effect.

Rarely recommends projects – guest commentator Xu Jinghong was deeply captivated by the project.

Investors rolled up their sleeves and showcased their resources.

In which application areas of directional sound technology can you think of? What other scenarios could it be applied to? Feel free to contact us for a "brainstorming" session!！
