During the 99 Commonweal Day project in 2023, after 2 years of technology accumulation, with the support of China Deaf Association, QQ Music, National singing, Cooli Music, Tianqin Lab and Tencent Public Welfare, Tencent SSV Silver hair Technology Lab, and China disabled Persons' Federation Public Welfare Organization-Tencent accessibility Joint Innovation Laboratory have integrated the capabilities of AI hearing analysis, wide dynamic range compression and hearing loss simulation on the basis of the original technology. Upgraded the original low-frequency music technology and launched the first batch of hearing-adapted low-frequency music to provide targeted music to users with different degrees of hearing loss and bring them a better and more complete music experience.

While introducing the technology of adapting listening to low-frequency music, QQ Music, National singing and Kuwo Music worked with Ayunga, the Legend of Phoenix, Gong Linna, Huang Yishan, Jiang Dawei, Xu Wei, Zhou Chuanxiong, Zheng Jun, Zhao Zhao and other love communicators to jointly create the public welfare album of the second season of "heard and inaudible Music".

Chen Feifei, vice president of public relations at QQ Music, said: "We hope to attract more musicians in the industry to pay attention to people with hearing impairment through the launch of hearing adaptation low-frequency music technology and the second season of hearing-inaudible music. join in the public welfare cause of low-frequency music, on the one hand, help public welfare organizations for people with hearing impairment to wear hearing aids. On the other hand, people with different degrees of hearing impairment can enjoy barrier-free 'sound activity' through the music platform. "

Devote two years to upgrading new technology to create a complete music experience for people with hearing impairment

It is understood that at present, there are many people with hearing impairment in China, including 120 million elderly people whose hearing is declining. It is not that they cannot hear, but because of high-frequency hearing loss, for example, when listening to music, they can only hear the drummer and bass but not the lead singer, unable to enjoy the beauty of the music. An old man once described his feeling of wearing headphones to listen to the music of "where the peach blossoms are in full bloom". Basically, what he heard was "the hometown of the peach blossoms", unable to listen to a complete song.

To this end, QQ Music released China's first low-frequency public welfare album "heard and inaudible Music" in 2021, which has been played more than 7000 times in the first year of launch.

Zhao Weifeng, head of audio technology at Tencent Music Tianqin Lab, said: "after the first attempt, in order to cover more people with hearing loss, provide more delicate barrier-free music suitable for people with different degrees of hearing impairment (especially those with high frequency hearing loss). We decided to upgrade the project to benefit a wider range of hearing impaired users."

This time, QQ Music painstakingly launched listening adaptation low-frequency music in two years, which can initially conduct a simple listening test on users in QQ Music's App, and measure the degree of hearing loss: mild, moderate, moderate to severe, severe, extremely severe and other hearing loss, and generate customized hearing compensation playlists. Users only need to conduct a simple test for 3 minutes in the function of the listening test, QQ Music can help users understand the scope of their hearing loss and get a list of low-frequency music that better matches their listening.

"We have designed a series of fast listening tests to help users check their listening within a few minutes." Cao Shuo, head of sound technology in QQ Music Galaxy, said, "in terms of the specific process, we are based on the national standard of" GB / T16296.1-2018 Acoustic audiometry ". We will test the left and right ears separately. After the test is completed, we will generate a hearing test report to help users understand their hearing impairment."

As the first technology for targeted low-frequency music provided by users with varying degrees of hearing loss, QQ Music made more fine and targeted adjustments in the process of making these songs into low-frequency music. Through the careful analysis of the original music and its structure, texture and orchestration, combined with classical hearing aids such as WDRC (Generalized dynamic range Compression) and Low-frequency (low frequency), the platform compensates the music for fine hearing loss. At the same time, in view of the common problems of the hearing impaired people, especially the elderly, such as the steep drop hearing curve, QQ Music also adjusted the audio to different degrees of hearing loss, so that people with different hearing loss can enjoy good listening. music that restores richness and beauty to the greatest extent.

In order to further expand the scope of attention, QQ Music also cooperated with the 2023 Youth Music Science and Technology training Project, which was just completed before. with the support of TME Music School and Tencent SSV innovative School Lab, more young people also actively participated in the production of the project, writing algorithms, mixing and other parts with the project team, making a contribution for people with hearing impairment to hear more beautiful music. At the same time, they also created a single "the most Beautiful Voice in the World" and invited the Oner group to sing for the public good, calling on everyone to pay attention to the psychology and life of people with hearing impairment.

Zhao Weifeng said: "We are constantly trying to combine music with science and technology to promote the popularization and development of public welfare music, so that every note can move people's hearts, no matter where they are, no matter what situation they face. Can enjoy the warmth and power of music."

"listening to inaudible Music" came online in the second season, making it barrier-free to listen to music.

At present, there have been many people with high-frequency hearing impairment in China, who may have more serious hearing impairment if they are not prevented as soon as possible. Wearing hearing aids correctly is one of the most important ways to improve hearing. But in fact, the utilization rate of hearing aids in China is still far lower than that in Europe and the United States and other developed countries and regions.

This time, QQ Music, National singing, Cool I Music launched the second season of "hear and not hear" Music and 99 Commonweal Day in-depth cooperation. Users can complete public welfare assistance and receive public welfare medals by searching for "99 commonweal Day" on three major platforms and completing relevant tasks in the special area. after the total number of assistance of the three platforms reaches 1 million, Tencent Charity Foundation will help 3000 elderly people to complete hearing science screening, hearing aid trial experience and intervention support.

Nine famous singers, including Ayunga, Legend of Phoenix, Gong Lina, Huang Yishan, Jiang Dawei, Xu Wei, Zhou Chuanxiong, Zheng Jun and Zhao Zhao, have also been invited to work together in the second season of hearing inaudible music. they have provided their own excellent music for the production of low-frequency music for listening, including classic songs such as "where the Peach Blossom is in full bloom", "Blue Lotus", "Free Flying" and "Twilight".

At the same time, Zhao Zhao will sing and parachute in the whole people and sing "when you are Old" with all the fans in the singing room, calling on everyone to care for the hearing health of the elderly.

Chen Feifei said that with the support of the China Association of the Deaf, the launch of the listening adaptation low-frequency playlist for "hearing and inaudible Music" in the second season not only enables hearing impaired users to enjoy complete music, but also provides intelligent and convenient preliminary suggestions for them to wear hearing aids through their hearing self-examination ability, which helps to stimulate more people's self-awareness of hearing health.

Music is not only an art, but also a medium of interpersonal communication. Music is of positive significance for hearing impaired users to better integrate into the society. In the follow-up, QQ Music, National singing and Kuwo Music will work with more singers to launch more low-frequency songs adapted to listening, just like building a barrier-free city, starting from every little thing around you, by constantly creating a barrier-free listening experience of music, so that hearing-impaired users can have a richer music entertainment life.
