Rishab Sachidanand, Feb 17, 2019 : Anyone who uses earphones/headphones a lot has experienced that they have to always set the volume of what they are listening to a certain level so that they are not disturbed by the surrounding noise, be it at the gym, while going for a run or just in a crowded area we always have to fiddle with the volume button to find the perfect balance between the earphone sound and the surrounding noise. My idea would be to develop an algorithm which senses (with the help of the mic in the earphone/headphone) how much noise is being produced outside and automatically change the volume to negate the noise, however this can be done only to a limit so as to avoid high volume levels. Who are the users? Just about anyone who use their handset for media consumption, however the main target audience would be runners, gymers, travelers and also people who spend majority of their time commuting or outside. Also, this could be targeted to people who use earphone/headphones with mics a lot. What is the proposed function? An algorithm (developed by Oneplus) which would sense/detect the amount of noise in the surrounding with the help of the mic in headset and according to the surrounding noise the handset can automatically change to a slightly higher volume in order to partially cancel out the surrounding noise. This can also be done in quiet environments where the mic can sense that there is not much noise and subsequently the handset and reduce the volume. This function can be given as an option to the user whether he wanted to turn on adaptive sound. What is the user value? Oneplus aims at providing a more immersive experience to the end user, however this experience can be disturbed by several external/surrounding factors and canceling out these factors would be really help boost the immersive experience. Now with this feature it would remove the need to always reach for your handset to change the volume or the volume control on the earphone/headphone and also one of the main benefits to this will be that the user is not listening to audio at volume levels that is considered harmful, when in a silent environment it reduces volume to reduce risks and in noisy environments it only increases to such an extent that it is not risky. If there are existing comparable functions in the smartphone industry, how is your proposed feature superior? To my knowledge I do not think there is any such function in the smartphone industry. The way people can use this function can be by two ways. The first one being when the user clicks the volume button there will be an option to toggle it on the volume slider and when it is tapped it switches on and changes the volume accordingly. The second method being is going to Settings > Sound > Adaptive sound.
