Hearing Sensitivity Acquisition Methods And Devices

1 - 14 . (canceled)

15 . A method for utilizing a vocalization of a user, comprising:

receiving an ear canal pick-up signal from an ear canal microphone of an earphone device, wherein the ear canal microphone detects a first voice;

receiving an ambient sound pick-up signal from an ambient sound microphone of the earphone device, wherein the ambient sound microphone detects the first voice and a second voice in an acoustic environment;

determining a vocalization of a user in the acoustic environment by separating the first voice from the second voice based on comparing the ear canal pick-up signal with the ambient sound pick-up signal; and

sending the vocalization to an application that utilizes the vocalization based on input from the user.

16 . The method of claim 15 , wherein determining the vocalization includes comparing a spectrum of the first voice from the ear canal pick-up signal with an ambient spectrum from the ambient sound pick-up signal.

17 . The method of claim 15 , wherein determining the vocalization includes parsing the ear canal pick-up signal and the ambient sound pick-up signal into blocks and performing a transform based on the blocks.

18 . The method of claim 15 , further comprising:

determining whether the user is in a noisy environment by measuring a sound pressure level (SPL) of the acoustic environment.

19 . The method of claim 15 , further comprising:

comparing a sound pressure level (SPL) of the acoustic environment to a threshold, wherein the SPL is determined based on a sampling by the ear canal microphone and the ambient sound microphone.

20 . The method of claim 15 , wherein the application utilizes the vocalization to perform a hearing test of the user.

21 . A device, comprising:

an ear canal microphone;

an ambient sound microphone;

a memory; and

a processor configured to execute instructions stored in the memory to:

receive an ear canal pick-up signal from the ear canal microphone, wherein the ear canal microphone detects a user's voice;

receive an ambient sound pick-up signal from the ambient sound microphone, wherein the ambient sound microphone detects the user's voice and a second voice in an acoustic environment;

determine a vocalization of a user in the acoustic environment by separating the user's voice from the second voice based on comparing the ear canal pick-up signal with the ambient sound pick-up signal; and

send the vocalization to an application that utilizes the vocalization based on input from the user.

22 . The device of claim 21 , wherein determining the vocalization includes comparing a spectrum of the user's voice from the ear canal pick-up signal with an ambient spectrum from the ambient sound pick-up signal.

23 . The device of claim 21 , wherein determining the vocalization includes parsing the ear canal pick-up signal and the ambient sound pick-up signal into blocks and determining an amplitude and phase based on the blocks.

24 . The device of claim 21 , wherein the processor is further configured to execute instructions stored in the memory to:

determine whether the user is in a quiet environment by measuring a sound pressure level (SPL) of the acoustic environment.

25 . The device of claim 21 , wherein the processor is further configured to execute instructions stored in the memory to:

compare a sound pressure level (SPL) of the acoustic environment to a standard for noise exposure, wherein the SPL is determined based on a sampling by the ear canal microphone and the ambient sound microphone.

26 . The device of claim 21 , further comprising:

a speaker, wherein the application utilizes the speaker to output sound into an ear canal of the user.

27 . The device of claim 21 , wherein the application utilizes the vocalization to measure frequency dependent hearing loss.

28 . A non-transitory computer readable medium storing instructions operable to cause one or more processors to perform operations comprising:

receiving an ear canal pick-up signal from an ear canal microphone of an earphone device, wherein the ear canal microphone detects a user's voice;

receiving an ambient sound pick-up signal from an ambient sound microphone of the earphone device, wherein the ambient sound microphone detects the user's voice and a second voice in an acoustic environment;

determining a vocalization of a user in the acoustic environment by separating the user's voice from the second voice based on comparing the ear canal pick-up signal with the ambient sound pick-up signal; and

sending the vocalization to an application that utilizes the vocalization based on input from the user.

29 . The non-transitory computer readable medium storing instructions of claim 28 , wherein determining the vocalization includes comparing a spectrum of the user's voice from the ear canal pick-up signal with an ambient spectrum from the ambient sound pick-up signal.

30 . The non-transitory computer readable medium storing instructions of claim 28 , performing a transform based on blocks parsed from the ear canal pick-up signal and the ambient sound pick-up signal.

31 . The non-transitory computer readable medium storing instructions of claim 28 , the operations further comprising:

measuring a sound pressure level (SPL) of the acoustic environment; and

determining whether the user is in a noisy or quiet environment based on the SPL.

32 . The non-transitory computer readable medium storing instructions of claim 28 , the operations further comprising:

comparing a sound pressure level (SPL) of the acoustic environment to an upper threshold level to determine a noisy environment and a lower threshold level to determine a quiet environment.

33 . The non-transitory computer readable medium storing instructions of claim 28 , wherein the application utilizes a speaker to output sound into an ear canal of the user.

34 . The non-transitory computer readable medium storing instructions of claim 28 , wherein the application utilizes the vocalization to perform a hearing test of the user.
