Detailed Description
Embodiments of the patent technical scheme of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for more clearly illustrating the technical solutions of the present patent, and therefore are only exemplary and should not be taken as limiting the scope of the present patent.
An embodiment, as shown in fig. 1, provides a hearing assistance method for an adaptive environment, including:
in step S101, receiving a real-time sound signal that is propagated to the hearing aid by the current environment;
in step S102, framing the acquired real-time sound signal;
in step S103, adding a timestamp identifier to the real-time sound signal of each frame under the condition of time sequence, so as to obtain a real-time sound signal with the timestamp identifier;
in step S104, normalization operation is performed on the real-time sound signals with the timestamp marks, and the switching state of the current environment is determined;
In step S105, a preset program is executed according to the switching state of the current environment, and the real-time sound signal transmitted to the hearing aid from the current environment is amplified according to the preset program;
In this embodiment, the framing process of the sound signal can be used to compare environmental changes over a time domain, as illustrated by: in a quieter environment, the characteristic change of the sound fragments of the framing process is small, the program defaults to execute one sound processing mode, and when the user moves to an area with larger external sound, the characteristic change of the sound fragments of the framing process is large, the program defaults to execute a second sound processing mode, so that the adaptability to the environment is enhanced.
In one embodiment, as shown in fig. 2, the processing of framing the acquired real-time sound signal includes:
in step S201, a setting program of the real-time sound signal to be framed is acquired;
in step S202, the real-time audio signals within the same time threshold are stored in frames according to the setting procedure of the real-time audio signals.
In this embodiment, the frame interval is between 0.01s and 0.1s, so that the sound information in the time domain can be thinned, and the selection of the time domain is between 5 seconds and 10 seconds, so that the influence of noise change in a short time on the switching program can be prevented.
In an embodiment, as shown in fig. 3, performing normalization operation on the adjacent real-time sound signals with the timestamp identifier, to determine a switching state of the current environment, including:
in step S301, a dynamic amplitude spectrum with a timestamp identifier is established for the real-time sound signal within a time threshold, and N adjacent dynamic amplitude spectrums with timestamp identifiers are sequentially compared;
In step S302, if the maximum range of the dynamic amplitude spectrum with the timestamp identifier is greater than the preset range, intercepting the amplitude of the dynamic amplitude spectrum within the preset range according to the first preset subroutine;
in the step, the first preset subroutine is a reasonable hearing threshold range of a user, and the frequency range which can be heard by normal human ears is 20 Hz-20000 Hz and is divided into 10dB-65 dB;
In step S303, if the N pairs of adjacent dynamic amplitude spectrum variation ranges with the timestamp marks exceed the preset variation range, selecting one operation switching subroutine according to the second preset subroutine;
In this step, the value range of N is a preset value, and examples are: the sound decibel quantity in a certain environment time domain is mostly distributed between 10dB and 15dB, the number of frames with sound size between 35dB and 40dB is detected to be 45, and the set value of N is 20, so the situation is considered as environment change;
In step S304, if the dynamic amplitude spectrum variation ranges with the timestamp marks are located in the preset variation ranges, the previous preset subroutine is continuously executed according to the third preset subroutine.
In this embodiment, the preset variation range is a preset value, for example: the sound decibel quantity in a certain environment time domain is mostly distributed between 10dB and 15dB, the value of the preset change range is 5dB, and thus the sound size between 5dB and 20dB is not considered to exceed the preset change range.
In one embodiment, as shown in fig. 4, selecting an operation switching subroutine according to the second preset subroutine includes:
In step S401, if the dynamic amplitude spectrum variation range with the timestamp identifier is located in the first preset sub-variation range, the intensity of the real-time sound signal is increased by N1 times according to the first switching subroutine;
In step S402, if the dynamic amplitude spectrum variation range with the timestamp identifier is located in the second preset sub-variation range, the intensity of the real-time sound signal is increased by N2 times according to the second switching subroutine;
in step S403, if the dynamic amplitude spectrum variation range with the timestamp identifier is located in the third preset sub-variation range, the intensity of the real-time sound signal is increased by N3 times according to the third switching subroutine;
Wherein the values of N1, N2 and N3 are sequentially reduced.
In this embodiment, the preset sub-ranges correspond to a switching sub-program, for example: the third preset sub-change range is larger than 20dB, the second preset sub-change range is 10dB-20dB, the first preset sub-change range is 5dB-10dB, and the values of N1, N2 and N3 are 1.1, 1.8 and 2.8 respectively, so that the excessive sound output can be limited, and the sound can be adjusted to the comfortable sound environment of a user.
In one embodiment, as shown in fig. 5, the amplifying the real-time sound signal transmitted to the hearing aid from the current environment according to the preset program includes:
In step S501, converting the real-time sound signal into a first electrical signal;
In step S502, the first electrical signal of the current environment is processed into a second electrical signal according to a preset program;
in step S503, the second electrical signal is converted into an amplified sound signal of the current environment;
