Apparatus and method for controlling personalised audio frequency equalizer
View Patent ↗Disclosed is a method of controlling a personalized audio frequency equalizer by an audio device for outputting a sound source The method includes: a user's age grasping step of grasping a user's age by inquiring the user's age; a user's hearing ability measurement step of measuring, for each frequency, the minimum audible volume; a personalized equalizer creation step of creating the personalized equalizer using a system test user hearing data (HTUHD) that the user may hear when a volume having a system test frequency is outputted, and an application test user hearing data (STUHD), which is a value of volume that the user may hear, while increasing a volume having an application test frequency; and a sound source output step of outputting a sound source through the personalized equalizer created at the personalized equalizer creation step.
1. A method of controlling a personalized audio frequency equalizer by an audio device for outputting a sound source, the method comprising:
(a) receiving a user's age by an input of a user via a user interface;
(b) setting a plurality of frequencies as test frequencies, including
(b1) setting a plurality of system test frequencies, which are frequencies of a sound source adjusted on hardware of the audio device,
(b2) setting a plurality of application test frequencies, which are frequencies of a sound source adjusted by sound source playback software installed in the audio device, and
(b3) excluding a preset frequency from the test frequencies if the user's age input by the user is equal to or greater than a preset age;
(c) measuring, for each test frequency, a minimum audible volume which the user is able to hear, including
(c1) measuring, for each system test frequency, the minimum audible volume as a system test user hearing data (HTUHD) that the user is able to hear when a test sound having a system test frequency is outputted,
(c2) calculating an average of the system test user hearing data (HTUHD) measured for each system test frequency as a system test hearing average value, and
(c3) measuring, for each application test frequency, the minimum audible volume as an application test user hearing data (STUHD) that the user is able to hear while maintaining the system test hearing average value on the hardware of the audio device and increasing a volume of a test sound having an application test frequency adjusted by the sound source playback software;
(d) creating the personalized equalizer using the system test user hearing data (HTUHD) and the application test user hearing data (STUHD); and
(e) outputting a sound source through the personalized equalizer created at the step (d).
2. The apparatus according to claim 1 , wherein the step (c1) includes
increasing a volume of the test sound for each test frequency, and
setting a volume value input by the user for each test frequency as the minimum audible volume of each system test frequency.
3. The apparatus according to claim 2 , wherein the plurality of system test frequencies include 64 Hz, 250 Hz, 1 kHz and 4 kHz, and the plurality of application test frequencies include 32 Hz, 64 Hz, 125 Hz, 256 Hz, 512 Hz, 1024 Hz, 2 kHz, 4 kHz, 8 kHz and 16 kHz, and
wherein the preset frequency excluded from the test frequencies if the user's age input by the user is equal to or greater than a preset age includes 16 kHz.
4. An apparatus for controlling a personalized audio frequency equalizer, the apparatus comprising:
a computing device configured to:
receive a user's age information input via a user interface;
set a plurality of system test frequencies, which are frequencies of a sound source adjusted on hardware of an audio device, as test frequencies;
set a plurality of application test frequencies, which are frequencies of a sound source adjusted by sound source playback software installed in the audio device, as the test frequencies;
exclude a preset frequency from the test frequencies if the user's age input by the user is equal to or greater than a preset age;
measure, for each system test frequency, a minimum audible volume as a system test user hearing data (HTUHD) that the user is able to hear when a test sound having a system test frequency is outputted;
calculate an average of the system test user hearing data (HTUHD) measured for each system test frequency as a system test hearing average value;
measure, for each application test frequency, a minimum audible volume as an application test user hearing data (STUHD) that the user is able to hear while maintaining the system test hearing average value on the hardware of the audio device and increasing a volume of a test sound having an application test frequency adjusted by the sound source playback software;
create the personalized equalizer using the system test user hearing data (HTUHD) and the application test user hearing data (STUHD); and
output a sound source through the personalized equalizer via a speaker.
5. The apparatus according to claim 4 , wherein the plurality of system test frequencies include 64 Hz, 250 Hz, 1 kHz and 4 kHz, and the plurality of application test frequencies include 32 Hz, 64 Hz, 125 Hz, 256 Hz, 512 Hz, 1024 Hz, 2 kHz, 4 kHz, 8 kHz and 16 kHz,
wherein the preset frequency excluded from the test frequencies if the user's age input by the user is equal to or greater than a preset age includes 16 kHz.
6. The apparatus of claim 4 , wherein, to measure the system test user hearing data (HTUHD), the computing device is configured to:
increase a volume of the test sound for each test frequency, and
set a volume value input by the user for each test frequency as the minimum audible volume of each system test frequency.
