Field of the Invention:
The invention relates to a method and a system for enhancing the listening experience of a user in relation to audio component. In particular, the invention relates to a method and a system for enhancing the listening experience of a user in relation to audio component by hyper-personalization of the audio component.
Background of the Invention:
Enhancing listening experience of a user in relation to audio component being played comprises many facets.
One traditional route allows the user to manipulate equalizer settings while playing the audio component. As a matter of fact, many of the audio players come with either a hardware based equalizer or a firmware based equalizer that divide the sound waves into a plurality of bands and allow the user to manipulate the amplitude of the sound waves in each band, thereby enhancing listening experience of the user in relation to the audio component being played.
Another traditional route attempts to reduce the background noise while playing the audio component. Generally, background noise (or ambient noise such as traffic, air-handling systems, etc.) are captured by a microphone. An electronic circuit then produces a noise-cancelling wave that is 180° out of phase with the background noise. The noise-cancelling wave is then output by a speaker (the speaker may additionally output the audio content), thereby enhancing listening experience of the user in relation to the audio component being played.
In yet another traditional route, attempt has been made to provide a system that divide the sound waves into a plurality of bands and manipulates the amplitude of the sound waves in each band based on the hearing profile of the user. Such systems are more commonly used as hearing-aid devices.
While enhancing the listening experience of a user in relation to audio component is an area of constant innovation, there still exists a need to improve the methods and systems involved in the same. For example, there exists a need to provide a method and a system for hyper-personalization of the audio component.

In an embodiment of the invention, the feedback of the first user is received using a user-interface selected from a group comprising an audio-based interface, gesture-based interface, eye tracking based interface, touch-based, brain-based adaptive interface and other interfaces.
In an embodiment of the invention the method may further comprise, the feedback of the first user may be indicative of a sound perception parameter. The sound perception parameter may be selected from a group comprising overall loudness level, normalised or absolute loudness of predetermined frequency bands, the spectral envelope shape, spectrographic features such as rising or falling pitch, the presence and normalised or absolute loudness of dominant narrow bands sounds, the presence or absence of odd and/or even harmonics, the presence and normalized or absolute loudness of noise, low-frequency periodicity, digital signal processor and compression, limiting, high-pass filters, low-pass filters, modulation, and equalization.
In one embodiment, headphones/earphone or speaker system or any other audio device
belonging to the user includes a microphone and an audio output speaker unit. They may be
connected to a mobile computation device by a wireless network such as Bluetooth or wifi or
Near Field Communication etc. Alternatively, a wire may be used to connect to the mobile
device. The microphone receives the environmental ambient sound and converts the received
sound electrical signals which pass through an ADC, which converts the sound signal to a
digital ambient sound signal. This happens, while the audio output speaker unit plays an
audio signal to the user, the software on the mobile computing device or desktop computer
records the user's response to the audio signal. This kind of audiometric measurements can
be done in many ways such as by an audiologist or by software or by signal processing
modules from an external source. In this embodiment as a reference, the processor measures
15

the user's response to input audio at reducing or increasing levels of frequencies and sound decibels until there is no measurable response or vice -versa from the user.
The invention records the data point at different intervals of the same response/no response. The audio signal lies in the range of audible frequencies for humans and is further divided into 10 bands for analysis. Some frequencies may also be available outside audible frequency range for the user to feel its effects and provide feedback. Every music content usually covers all these bands, thus making the customer chooses his favourite song, distributing it in 10 frequency bands or more/ less depending on the accuracy of the test, applying different personalization on the same content as per a particular band and making the user choose the one which perceptively sounds better to him/her may be a version of making the user hearing profile. The process of enhancement of the content and hearing correction in this method is happening simultaneously (parallelly) or serially one after the other.
In an embodiment of the invention the method, the content being consumed, the system can do pre-analysis of the content and modify the signal accordingly. The hearing profile determined of the user may be compared with the sound profiles stored in the memory to determine if the memory holds a stored sound profile that "matches" (e.g. - is the same or reasonably similar) to the profile determined. This is done by measuring the delta change between the parameters of the sound profiles. If it is below a particular threshold then it matches, else not. Threshold can be set by us subjectively to the environmental and demographic conditions of the user. The modifications preferred by a set of other users with which the profile match has resulted as positive is applied to the user's profile for feedback and enhancement of the experience. Therefore increasing the user's immersion of the content the user may be consuming and specific to that particular content itself.
For the first user his characteristics are fed into the system by the user and compared with other users to be unique in nature or not. If it is found to be completely unique then for that type of user, a user print is created and taken to be a benchmark of a new class of users.
There are many methods which can be used to produce a positive or negative match. Every user sound profile, for example, consists of an ordered set of n numbers representing various parameters of the sound as previously described. Thus this sound profile may be considered as vectors in an n-dimensional space. The similarity metric used for comparison of the sound profile and the other user's sound profile may then be spectral or spectrographic

comparisons, Euclidean distance between the vectors or any other required method. Based on the match a similarity metric may be defined. A lower value in similarity metric may mean greater deviation between the profiles however a higher number may mean more similarity or visa-versa. The invention arises from a need that the signal modified for the consumption of movie content may be very different from the signal modified for the consumption of audiobook content etc. Perfect hearing does not imply equivalence to desired hearing. A hearing without any hearing loss of the user may not produce complete immersion. In fact, what matters more is the perception of hearing which may be quite different from ideal hearing.
Every individual sound profile may include many characteristics such as for example - an overall loudness level, normalized or absolute loudness of predetermined frequency bands, the spectral envelope shape, spectrographic features such as rising or falling pitch, the presence and normalized or absolute loudness of dominant narrow bands sounds, the presence or absence of odd and / or even harmonics, the presence and normalised or absolute loudness of noise, low frequency periodicity and other characteristics.
To establish functioning of the invention the following tests were conducted:-
• A set of 20 consumers were divided into 4 groups of 5 each . Each group was divided based on the following parameters.
• Group 1: Individuals having similar hearing profile but different demographics and taste in music.
• Group 2: Individuals having similar demographics as that of the first user but different hearing profiles and taste in music.
• Group 3: Individuals having similar taste in music under similar environmental noise conditions but different hearing profile and demographics.
• Group 4: Individuals having similar hearing profile as Group 1, demographics as Group 2 and similar taste in music under similar environmental conditions as Group 3.

• The groups individually were subjected to a particular content A,B and C at random and were asked to give their rating on the likeability of that content A. Content A was chosen such that it was not likeable by any of the groups but Group 1. Similar content B was chosen so to the like ability of demographic profile of Group 2 and content C was chosen to the taste of Group 3.
All three content was also subjected to Group 4 and their feedback was noted.
• The results over a period of a few days were tracked and likeability (average of the
individuals in the group ) score came out as follows.
The qualitative inference we drew from the above experiment was that individuals having all three conditions intact such as in Group 4 were much more likely to like the song and according to their perception, preferred it.
As you can see, content A was preferred by Group 4 more than Group 1. Content B was preferred by Group 4 more than Group 2. Content C was preferred by Group 4 more than Group 3.
This leads us to believe that the modification of content on the basis of the parameters for a neutral individual would result in a better experience of the content for the individual, if all parameters are considered together, rather than individually.
