stream from a server to a client over a communications network, processing the audio signal by means of a processing unit to match an optimal hearing profile of a user listening to the audio at the client, characterized in that the processing unit is arranged at the server or in the communications network, between the server and the client. ## Claims ### Claim 1 A method for personalizing the audio signal of an audio or video stream, comprising: sending the audio or video stream from a server to a client over a communications network, processing the audio signal by means of a processing unit to match an optimal hearing profile of a user listening to the audio at the client, characterized in that the processing unit is arranged at the server or in the communications network, between the server and the client. ### Claim 2 (depends on 1) The method according to claim 1, wherein the communications network is a cloud computing network. ### Claim 3 (depends on 1) The method according to claim 1, wherein the optimal hearing profile is established by measuring the response of one or two of the user's ears to a test signal, comparing the measured response to a target response, obtaining deviations between the measured response and the target response, and adjusting the audio signal based on the obtained deviations. ### Claim 4 (depends on 1) The method according to claim 1, wherein the optimal hearing profile is stored on a storage device. ### Claim 5 (depends on 4) The method according to claim 4, wherein the storage device is a storage server, a computer, such as a personal computer or a handheld computer, a mobile communications device, a multimedia device, a smartphone or a tablet. ### Claim 6 (depends on 4) The method according to claim 4, wherein the optimal hearing profile is stored as a personalized code, such as a QR-code. ### Claim 7 (depends on 4) The method according to claim 4, wherein the processing unit accesses the storage device over the communications network. ### Claim 8 (depends on 1) The method according to claim 1, wherein the optimal hearing profile comprises a frequency response of one or both of the user's ears. ### Claim 9 (depends on 1) The method according to claim 1, wherein the optimal hearing profile is established by means of otoacoustic emissions (OAE). ### Claim 10 (depends on 1) The method according to claim 1, wherein the optimal hearing profile is established by means of a test device or software test program at the client. ### Claim 11 (depends on 10) The method according to claim 10, wherein the test device or software test program is connected to, or comprised by, a computer, such as a personal computer or a handheld computer, a mobile communications device, a multimedia device, a smartphone or a tablet. ### Claim 12 (depends on 1) The method according to claim 1, wherein a first, earlier optimal hearing profile is established, as well as a second, later optimal hearing profile and a difference between the first and second optimal hearing profiles is determined. ### Claim 13 (depends on 12) The method according to claim 12, comprising the step of forecasting a third, future optimal hearing profile based on the difference between the first and second optimal hearing profiles. ### Claim 14 (depends on 1) The method according to claim 1, comprising the step of predicting the optimal hearing profile based on estimated hearing deterioration data. ### Claim 15 (depends on 1) The method according to claim 1, comprising the step of forecasting a third, future, optimal hearing profile based on estimated hearing deterioration data. ### Claim 16 (depends on 1) The method according to claim 1, wherein the audio signal is processed in real-time. ### Claim 17 (depends on 1) The method according to claim 1, wherein substantially 100% of the audio signal processing takes place at the processing unit arranged at the server or in the communications network, between the server and the client. ### Claim 18 (depends on 1) The method according to claim 1, wherein multiple users associated with multiple clients are present and the processing unit processes the audio signal to match the optimal hearing profile of each individual user listening to the audio at the associated client. ### Claim 19 (depends on 1) The method according to claim 1, wherein multiple processing units are arranged at the server or in the communications network, between the server and the client. ### Claim 20 A storage device, for instance as a storage server, a computer, such as a personal computer or a handheld computer, a mobile communications device, a multimedia device, a smartphone or a tablet for personalizing the audio signal of an audio or video stream, comprising: sending the audio or video stream from a server to a client over a communications network, processing the audio signal by means of a processing unit to match an optimal hearing profile of a user listening to the audio at the client, characterized in that the processing unit is arranged at the server or in the communications network, between the server and the client. ### Claim 21 (depends on 20) The storage device according to claim 20, wherein the optimal hearing profile is stored as a personalized code, such as a QR-code. ### Claim 22 (depends on 20) The storage device according to claim 20, wherein the storage device can be accessed by the processing unit over the communications network. ### Claim 23 A test device or software test program for personalizing the audio signal of an audio or video stream, comprising: sending the audio or video stream from a server to a client over a communications network, processing the audio signal by means of a processing unit to match an optimal hearing profile of a user listening to the audio at the client, characterized in that the processing unit is arranged at the server or in the communications network, between the server and the client, the test device or software test program for connection to, or to be comprised by, a computer, such as a personal computer or a handheld computer, a mobile communications device, a multimedia device, a smartphone or a tablet.
