Systems, devices and methods for fitting hearing assistance devices
Embodiments herein relate to systems, devices and methods for fitting hearing assistance devices. In a first aspect, a method of fitting a hearing assistance device is included, the method including providing an audio sample to a hearing assistance device wearer, receiving input from the hearing assistance device wearer regarding a preferred sound volume or perceived loudness, receiving input from the hearing assistance device wearer with the external device regarding a bass/treble balance, and determining a maximum power output of the hearing assistance device that does not exceed a loudness discomfort level (LDL). Other embodiments are also included herein.
1. A method of fitting a hearing assistance device comprising:
providing an audio sample to a hearing assistance device wearer;
determining a degree of hearing impairment of the hearing assistance device wearer;
comparing the determined degree of hearing impairment to a threshold level of impairment;
preventing the hearing assistance device wearer from continuing a device fitting process if the determined degree of hearing impairment is greater than the threshold level of impairment;
qualifying a sound field in which the hearing assistance device wearer is present;
manipulating the audio sample provided to the hearing assistance device wearer based on acoustic properties of the sound field;
receiving input from the hearing assistance device wearer regarding a preferred sound volume or perceived loudness;
receiving input from the hearing assistance device wearer regarding a bass/treble balance; and
determining a maximum power output of the hearing assistance device that does not exceed a loudness discomfort level (LDL).
2. The method of claim 1 , further comprising receiving input from the hearing assistance device wearer regarding a binaural balance using an external device and sending programming data from the external device to the hearing assistance device based on the received input, the programming data comprising device setting values, wherein the external device converts the received input from the hearing assistance device wearer and the determined maximum power output into the device setting values, wherein the device setting values are specific to a type of hearing assistance device.
3. The method of claim 1 , wherein receiving input from the hearing assistance device wearer regarding a bass/treble balance comprises presenting the hearing assistance device wearer with a first plurality of preselected bass/treble balance settings and receiving input from the hearing assistance device wearer regarding preference.
4. The method of claim 3 , further comprising presenting the hearing assistance device wearer with a second plurality of preselected bass/treble balance settings based on received preference input.
5. The method of claim 1 , wherein the operation of providing an audio sample to a hearing assistance device wearer comprises at least one of
wirelessly streaming the audio sample to the hearing assistance device;
playing the audio sample through an induction loop and receiving an audio sample signal through a telecoil or magnetic sensor;
accessing data stored on the hearing assistance device representing the audio sample;
playing the audio sample through a speaker of an external device; and
prompting an individual to generate the audio sample.
6. The method of claim 1 , wherein the operation of providing an audio sample to a hearing assistance device wearer comprises both
streaming the audio sample to the hearing assistance device; and
playing the audio sample through speakers of an external device.
7. The method of claim 1 , further comprising qualifying the device wearer based on a severity of their hearing impairment or based on a perceived hearing handicap.
8. The method of claim 7 , wherein qualifying the device wearer comprises presenting the device wearer with a panel of queries directed to the severity of their hearing impairment or their perceived hearing handicap and receiving feedback from the device wearer regarding the same.
9. The method of claim 8 , further comprising estimating the severity of their hearing impairment or their perceived hearing handicap based on the device wearer's feedback.
10. The method of claim 7 , wherein qualifying the device wearer comprises presenting the device wearer with a series of audio samples and questions regarding content of the same.
11. The method of claim 1 , further comprising qualifying the device wearer based on settings for a previous device configured for the device wearer.
12. The method of claim 1 , wherein qualifying the sound field comprises evaluating at least one of evaluating echoes, reverberation time, decay time, critical distance, room impulse measure, absorption coefficient across a human detectable frequency band, ambient noise, comb filter distortion, coloration distortion, early reflection, and late reflection.
13. The method of claim 1 , wherein qualifying the sound field comprises emitting a sample sound and evaluating sound received at the hearing assistance device or an external device.
14. The method of claim 1 , further comprising
presenting the device wearer with a series of audio samples and questions regarding content of the same; and
receiving answers to the questions from the device wearer.
15. The method of claim 14 , further comprising calculating an accuracy score based on the received answers and initiating a corrective measure if the accuracy score crosses a threshold value.
16. The method of claim 15 , the corrective measure comprising notifying the device wearer that they should contact a care provider and terminating the fitting procedure.
17. The method of claim 1 , further comprising
recording speech from the device wearer; and
evaluating the recorded speech to classify a degree or configuration of hearing loss of the device wearer.
18. The method of claim 1 , further comprising
determining a location of the device wearer;
evaluating regulations for device fitting based on the location; and
terminating or modifying the fitting procedure or notifying the device wearer that they should contact a care provider based on the regulations.
19. A hearing assistance device fitting system comprising:
a hearing assistance device comprising
a control circuit;
a microphone in electrical communication with the control circuit;
an electroacoustic transducer for generating sound in electrical communication with the control circuit;
a power supply circuit in electrical communication with the control circuit; and
an external device in wireless communication with the hearing assistance device;
wherein the system is configured to
provide an audio sample to a hearing assistance device wearer;
determine a degree of hearing impairment of the hearing assistance device wearer;
compare the determined degree of hearing impairment to a threshold level of impairment;
prevent the hearing assistance device wearer from continuing a device fitting process if the determined degree of hearing impairment is greater than the threshold level of impairment;
receive input from the hearing assistance device wearer;
receive input from the hearing assistance device wearer regarding a bass/treble balance; and
determine a maximum power output of the hearing assistance device that does not exceed a loudness discomfort level (LDL).
20. The hearing assistance device fitting system of claim 19 , wherein the threshold level of impairment corresponds to a degree of hearing impairment that is severe or greater.
