standard sound pressure level refers to the acoustic information for assigned frequency, and normal human ear just can perceive its sound pressure level existed.
In embodiments of the present invention, first export the acoustic information of assigned frequency with standard sound pressure level, and judge whether user can hear this standard sound pressure level.
In step s 102, receive the instruction that user inputs according to described standard sound pressure level, and regulate sound pressure level, to determine that reference sound intensity is arbitrarily downgraded according to the instruction that described user inputs.
In embodiments of the present invention, the instruction of user's input comprises the first instruction and the second instruction.If receive the first instruction of user's input, then show that user can't hear and receive the front sound pressure level exported of the first instruction; If receive the second instruction of user's input, then show that user can hear and receive the front sound pressure level exported of the second instruction.Here, the first instruction that user inputs according to standard sound pressure level if receive, then show that user can't hear the acoustic information of the assigned frequency exported with standard sound pressure level; If receive the second instruction that user inputs according to standard sound pressure level, then show that user can hear with the acoustic information of the assigned frequency of standard sound pressure level output.Instruction according to user's input regulates sound pressure level gradually, to determine that reference sound intensity is arbitrarily downgraded, thus detects at the hearing level of assigned frequency user on the basis that reference sound intensity is arbitrarily downgraded.
In step s 103, the basis that described reference sound intensity is arbitrarily downgraded reduces sound pressure level gradually with the first preset value, until receive the first instruction of described user input, sound pressure level is improved gradually again with the second preset value, until receive the second instruction of described user input, and the described sound pressure level before receiving described second instruction is defined as first sound arbitrarily downgrades, described first preset value is greater than described second preset value.
Here, the first preset value can be 10dB, and the second preset value can be 5dB, in this no limit.
In embodiments of the present invention, reduce sound pressure level gradually with the first preset value and refer to the first preset value reduction sound pressure level, and after the second instruction at every turn receiving user's input, then reduce sound pressure level with the first preset value; Reduce sound pressure level gradually with the second preset value to refer to the second preset value reduction sound pressure level, and after the second instruction at every turn receiving user's input, then reduce sound pressure level with the second preset value; Improve sound pressure level gradually with the first preset value to refer to the first preset value raising sound pressure level, and after the first instruction at every turn receiving user's input, then improve sound pressure level with the first preset value; Improve sound pressure level gradually with the second preset value to refer to the second preset value raising sound pressure level, and after the first instruction at every turn receiving user's input, then improve sound pressure level with the second preset value.
Such as, reference sound intensity is arbitrarily downgraded as 20dB, on the basis that reference sound intensity is arbitrarily downgraded, reduces sound pressure level to 10dB with 10dB; If export the acoustic information of assigned frequency with 10dB after, receive the first instruction of user's input, then improve sound pressure level to 15dB with 5dB; If export the acoustic information of assigned frequency with 15dB after, receive the first instruction of user's input, then improve sound pressure level to 20dB with 5dB; If export the acoustic information of assigned frequency with 20dB after, receive the first instruction of user's input, then improve sound pressure level to 25dB with 5dB; If export the acoustic information of assigned frequency with 25dB after, receive the second instruction of user's input, then 25dB is defined as first sound and arbitrarily downgrades.
In step S104, arbitrarily downgrade according to described first sound and determine the hearing level of described user in described assigned frequency.
As one embodiment of the present of invention, directly arbitrarily downgrade according to first sound and determine the hearing level of user in assigned frequency.
Fig. 2 shows the specific implementation flow chart of the listening checking method step S104 that the embodiment of the present invention provides, with reference to Fig. 2:
In step s 201, N sound pressure level is reduced with described first preset value, described sound pressure level is improved gradually again with described second preset value, until receive the second instruction of described user input, and the described sound pressure level before receiving described second instruction is defined as N+1 sound pressure level, wherein, N be more than or equal to 1 integer;
In step S202, arbitrarily downgrade to described N+1 sound pressure level according to described first sound and determine the hearing level of described user in described assigned frequency.
Such as, first sound is arbitrarily downgraded as 25dB, on the basis that first sound is arbitrarily downgraded, reduces sound pressure level to 15dB with 10dB, then improves sound pressure level to 20dB with 5dB; If export the acoustic information of assigned frequency with 20dB after, receive the second instruction of user's input, then 20dB is defined as the rising tone and arbitrarily downgrades.On the basis that the rising tone is arbitrarily downgraded, reduce sound pressure level to 10dB with 10dB, then improve sound pressure level to 15dB with 5dB; If export the acoustic information of assigned frequency with 15dB after, receive the first instruction of user's input, then improve sound pressure level to 20dB with 5dB; If export the acoustic information of assigned frequency with 20dB after, receive the second instruction of user's input, then 20dB is defined as the 3rd sound pressure level.On the basis of the 3rd sound pressure level, reduce sound pressure level to 10dB with 10dB, then improve sound pressure level to 15dB with 5dB; If export the acoustic information of assigned frequency with 15dB after, receive the first instruction of user's input, then improve sound pressure level to 20dB with 5dB; If export the acoustic information of assigned frequency with 20dB after, receive the first instruction of user's input, then improve sound pressure level to 25dB with 5dB; If export the acoustic information of assigned frequency with 25dB after, receive the second instruction of user's input, then 25dB is defined as the falling tone and arbitrarily downgrades.On the basis that the falling tone is arbitrarily downgraded, reduce sound pressure level to 15dB with 10dB, then improve sound pressure level to 20dB with 5dB; If export the acoustic information of assigned frequency with 20dB after, receive the first instruction of user's input, then improve sound pressure level to 25dB with 5dB; If export the acoustic information of assigned frequency with 25dB after, receive the second instruction of user's input, then 25dB is defined as fifth sound and arbitrarily downgrades.Can determine that first sound is arbitrarily downgraded as 25dB thus, the rising tone is arbitrarily downgraded as 20dB, and the 3rd sound pressure level is 20dB, and the falling tone is arbitrarily downgraded as 25dB, and fifth sound is arbitrarily downgraded as 25dB.
As one embodiment of the present of invention, calculate first sound and arbitrarily downgrade to the meansigma methods of N+1 sound pressure level, and meansigma methods is defined as the hearing level of user in assigned frequency.
Preferably, described arbitrarily downgrading to described N+1 sound pressure level according to described first sound determines that described user is specially at the hearing level of described assigned frequency:
The sound pressure level that frequency is maximum to described N+1 sound pressure level of being arbitrarily downgraded by described first sound is defined as the hearing level of described user in described assigned frequency.
As an alternative embodiment of the invention, the sound pressure level that frequency is maximum to N+1 sound pressure level of being arbitrarily downgraded by first sound is defined as the hearing level of user in assigned frequency.Such as, first sound is arbitrarily downgraded as 25dB, and the rising tone is arbitrarily downgraded as 20dB, and the 3rd sound pressure level is 20dB, the falling tone is arbitrarily downgraded as 25dB, and fifth sound is arbitrarily downgraded as 25dB, then sound pressure level is the frequency of 25dB is 3, sound pressure level is the frequency of 20dB is 2, therefore, 25dB is defined as the hearing level of user at 1kHz.
As an alternative embodiment of the invention, after determining the (n+1)th sound pressure level, judge first sound arbitrarily downgrades to the (n+1)th sound pressure level, whether to there is M equal sound pressure level, wherein, n is the integer being more than or equal to 1 and being less than or equal to N, and M is the integer being more than or equal to 2 and being less than or equal to n.If judge, first sound is arbitrarily downgraded to the (n+1)th sound pressure level, to be there is M equal sound pressure level, then this equal sound pressure level is defined as the hearing level of user in assigned frequency.If judge, first sound is arbitrarily downgraded to the (n+1)th sound pressure level, to be there is not M equal sound pressure level, then continue to determine next sound pressure level, there is the individual equal sound pressure level of M in all sound pressure levels determined until current, then this equal sound pressure level is defined as the hearing level of user in assigned frequency.It should be noted that, in embodiments of the present invention, after determining the (n+1)th sound pressure level, if judge, first sound is arbitrarily downgraded to the (n+1)th sound pressure level, to be there is M equal sound pressure level, then no longer continue to determine the n-th+2 sound pressure levels, directly arbitrarily downgrade to the (n+1)th sound pressure level according to first sound and determine the hearing level of user in assigned frequency.Such as, M equals 3, first sound is arbitrarily downgraded as 25dB, the rising tone is arbitrarily downgraded as 20dB, 3rd sound pressure level is 20dB, and the falling tone is arbitrarily downgraded as 25dB, and fifth sound is arbitrarily downgraded as 25dB, arbitrarily downgrade to fifth sound due to first sound and to arbitrarily downgrade the equal sound pressure level 25dB of middle existence 3, therefore 25dB is defined as the hearing level of user at 1kHz.Again such as, M equals 3, and first sound is arbitrarily downgraded as 25dB, and the rising tone is arbitrarily downgraded as 25dB, and the 3rd sound pressure level is 25dB, there are 3 equal sound pressure level 25dB, therefore 25dB is defined as the hearing level of user at 1kHz because first sound is arbitrarily downgraded to the 3rd sound pressure level.Again such as, M equals 3, first sound is arbitrarily downgraded as 25dB, and the rising tone is arbitrarily downgraded as 20dB, and the 3rd sound pressure level is 20dB, the falling tone is arbitrarily downgraded as 25dB, due to first sound arbitrarily downgrade arbitrarily downgrade to the falling tone in there are not 3 equal sound pressure levels, therefore continue to determine that fifth sound is arbitrarily downgraded, if fifth sound is arbitrarily downgraded as 25dB, then first sound is arbitrarily downgraded to fifth sound and to be arbitrarily downgraded the equal sound pressure level 25dB of middle existence 3, therefore 25dB is defined as the hearing level of user at 1kHz.

In step S403, described sound pressure level is improved gradually with described second preset value in the basis of described 6th value, until receive described second instruction of described user input, and using the described sound pressure level that receives before described first instruction as the 7th value;
In step s 404, described 7th value is defined as described reference sound intensity to arbitrarily downgrade.
Such as, the standard sound pressure level that 1kHz is corresponding is 40dB, if user is the first instruction according to the instruction that 40dB inputs, then on the basis of standard sound pressure level, improves sound pressure level to 50dB with 10dB; If export the acoustic information of assigned frequency with 50dB after, receive the second instruction of user's input, then 50dB is worth as the 5th, using 40dB as the 6th value; On the basis of the 6th value, improve sound pressure level to 45dB with 5dB; If export the acoustic information of assigned frequency with 45dB after, receive the second instruction of user's input, then 45dB is worth as the 7th, and 45dB is defined as basic sound pressure level.
