Problems solved by technology

[0021] However, in the structures disclosed in the above-mentioned prior patent documents 1 and 2, although sound information or hearing aid operations in daily life situations can be recorded, the user's response to the hearing aid at that time is not recorded. How to feel the ambient sound
In addition, in the technology of Patent Document 3, although the user's intention is indirectly recorded by pressing a button in an uncomfortable situation, what kind of auditory situation is not sufficiently recorded
In such a structure, there is a problem that, in any case, only by observing the log data at a hearing aid store, the most necessary information of the user's hearing at that time cannot be directly recorded.

Embodiment approach 1

[0085] image 3 The configuration of the electroencephalogram recording device 100 is shown. The electroencephalogram recording device 100 records the electroencephalogram reaction of the user 1 to the environmental sound 9 .

[0086] The electroencephalogram recording device 100 includes: a sound collection unit 2 ; a classification unit 3 ; an accumulation determination unit 4 ; an electroencephalogram measurement unit 5 ; and an accumulation unit 6 .

[0087] The sound collecting unit 2 includes, for example, a microphone and a sound input circuit as described later. The sound collecting unit 2 collects the environmental sound 9 and outputs it to the classifying unit 3 . The sound collecting unit 2, for example, samples and quantizes the collected sound, digitizes it, and outputs it as sound data. The audio data is, for example, 44.1 KHz, 16-bit data encoded by the linear PCM method if the audio quality is equivalent to that of a CD. Furthermore, the encoding method, sa...

Embodiment approach 2

[0177] In this embodiment, an electroencephalogram recording device will be described which, in addition to the configuration of the first embodiment, also has a configuration in which the evaluation of electroencephalograms is performed in the device and the criteria for accumulation determination are corrected based on the result.

[0178] It is known that the difference in the hearing state of users who need hearing aids is greater than that of normal hearing people, and the necessary part of the data may not be able to be fully accumulated for the number of times of accumulation of the volume of the sound originally set. Therefore, when a certain level of electroencephalogram data is accumulated, simple evaluation is performed, and the accumulated amount is corrected using the result, thereby enabling correspondence with users of various auditory states. If this function does not exist, it is necessary to check the accumulated data at a hearing aid store, first confirm that...

Embodiment approach 3

[0203] In the present embodiment, it is assumed that the adjustment is automatically performed inside the hearing aid by incorporating a data recording function and an evaluation function in the hearing aid main body without performing fitting by an expert at a hearing aid store.

[0204] Figure 19 The structure of the hearing aid 110 of this embodiment is shown. The hearing aid 110 includes, for example, the electroencephalogram recording device 100 and the hearing aid unit 101 according to the first embodiment. exist Figure 19 in, for image 3 The same structural elements use the same symbols, and descriptions are omitted. The configuration of the present embodiment is configured by adding the hearing evaluation unit 8 and the hearing aid unit 101 to the configuration of the first embodiment.

[0205] The hearing evaluation unit 8 is a part that performs hearing evaluation using the data of the accumulation unit 6 . basically implement the Figure 13B or Figure 14 ...

Abstract

The objective of the present invention is to suitably record ambient environmental sound and information related to hearing of a user at the time in order to collect data of a volume of data necessary for fitting at a hearing aid store. This electroencephalograph is provided with a sound collection unit which generates sound data of sound of the outside, an electroencephalography unit for generating brain wave data of brain waves of a user, a classification unit for classifying the collected sound into a plurality of divisions which have been pre-defined in relation to sound pressure, an accumulation assessment unit for assessing whether or not to record the brain wave data on the basis of whether the number of times of data accumulation has reached a pre-set target value for the divisions into which the sound has been classified, and an accumulation unit for associating the brain wave data and the sound data and accumulating thereof if an assessment has been made to record the brain wave data. A target value is set for each division so that when the target value of a first division, into which sounds of an expected minimum value are classified, is treated as a first value, and the target value of a second division, into which sounds of sound pressure greater than the minimum value are classified, is treated as a second value, the first value is set so that the first value becomes greater than or equal to the second value for the accumulation assessment unit.

Description

technical field [0001] The present invention relates to a technology for recording data used for adjustment of hearing aids. More specifically, the present invention relates to a device, method and program for recording sounds heard by the user in various daily sound environments and brain wave data reflecting the auditory state of the sounds. Background technique [0002] In recent years, due to the aging of society and the increase in opportunities to listen to loud music for a long period of time, the number of elderly or acoustically hard of hearing is increasing. In addition, with the downsizing and high performance of hearing aids, the threshold for wearing hearing aids has become lower, and the number of users using hearing aids for the purpose of improving listening to everyday conversations is increasing. [0003] A hearing aid is a device for assisting a user's impaired hearing by amplifying the amplitude of a signal of a specific frequency among various frequenci...
