Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a flowchart of the alerting voice signal conversion method of the present invention. External sounds are collected from sound collectors provided on both sides of the apparatus body such as glasses, for example, on the left and right frames of the glasses (sound collecting step S1).

The sound collected from the sound collector is FFT
(Fast Fourier Transform) and the like, and at the same time, into audio frequency components such as audio frequency values and vibration energy (audio signal conversion step S2). Process S
The audio frequency component converted by 2 is compared with a preset threshold value (comparing step S3). That is, the audio frequency components converted in step S2 are A1, A2, A3
..., assuming that the threshold value is A0, A1, A2,
.. And A0 are compared.

As a result, when the audio frequency component is less than the threshold value (for example, A1 <A0), the audio frequency component (A1) is stored in a storage unit such as a memory (first storage step S4). If the audio frequency component is equal to or larger than the threshold value (for example, A2> A0 or A2 = A0), step S4
(Eg A2)
−A1) is obtained by a calculation process (first calculation step S5).

The calculation result (A2-A1) in step S5
= B1) is stored in a storage unit such as a memory (second storage step S6). The above steps S1 to S6 are performed for each of the sounds collected from the pair of sound collectors (the other is shown as steps S1 'to S6', and in the following description, the sound frequency components are shown on the right shoulder). With a dash).

A′−A1 ′ = D1 ′) is obtained (third operation step S9). The calculation results (D1, D2) of steps S8 and S9
D1 ') is stored in a storage unit such as a memory (third storage step S10).

Thereafter, the alerting voice frequency component set in advance according to the content of the alert is compared with the audio frequency component stored in step S10, and the closest alerting voice frequency component among the alerting voice frequency components is compared. An audio frequency component is selected (comparing step S11). The alert sound frequency components stored in the memory or the like in advance include a running sound of a car, a sound of a horn, an alarm at a railroad crossing, and a ringing sound of a telephone. Since these have specific frequency components (frequency values, vibration energy of sound, etc.), these are stored in advance in a memory as a sounding voice frequency component in a memory or the like. The alarm at the railroad crossing is defined in advance as yellow, and the horn sound is defined as red.

In the next step S12, a command signal for specifying the contents of the alert is output based on the result of the comparison in step S11 (output step). The control device can determine whether the sound is coming from the left or right direction based on the calculation result of step S7. By monitoring the calculation result of step S5 at regular intervals, the sound source approaches or moves away. Can be determined. In this case, by changing the blinking time of the light emitting diode or the like according to the calculation result in the step S5 for each time, a change in the distance to the sound source can be notified to a deaf person or the like.

As means for clearly indicating the contents of the alert,
A warning level may be displayed by a plurality of luminescent colors to appeal to the visual sense of a deaf person or the like, or vibration by a vibrating body or display of characters may be used. Although one embodiment of the alert signal conversion method of the present invention has been specifically described,
The present invention is not limited at all by the above embodiment.

For example, only one sound collector is provided, and step S1
By providing the steps from to S5, it is possible to notify only the alert level. Step S
By adding 8 and S9, it is possible to determine whether the sound source is approaching or distant even when there is only one sound collector. As described above, according to the present invention, depending on whether the number of sound collectors is one or two, steps S1 to S5 are appropriately changed to steps S6, S7, and S5.
8, S9 can be added.
