Description

FIELD OF THE INVENTION [0001] The present invention relates to a sound field inspection system and a small sound booth including the sound field inspection system and a small audiometric booth including the system,

Field of the Invention [0002] The present invention relates to a sound field inspection technique, and more particularly, to a sound field inspection system having a structure suitable for a compact soundproof booth and a compact soundproof booth including the system.

Millions of people worldwide now suffer from hearing impairment, many of whom are unaware of their hearing loss. Reduced hearing abilities can be due to a variety of factors including age, health, occupation, injury and illness. Hearing loss can greatly reduce the quality of life, impair the relationship, and reduce access to employment. Recently, the use of sound equipment, the increase in the proportion of elderly people, and the increase in the noise environment, the number of hearing impaired people is increasing, and the demand for hearing aids is rapidly increasing, and the development of high performance digital hearing aids Is accelerating.

In general, a hearing test is a test that measures the degree of hearing sensitivity, such as whether a sound or voice is audible. Audiometer, which is a signal generator that generates a pure tone of the size and frequency that can be changed by the operator (doctor, audiologist) in order to perform hearing test, is used to measure the hearing and diagnose the audiologist's degree of hearing . The hearing test usually focuses on frequencies in the range of 250 Hz to 8 kHz, because this range includes sounds necessary for effective communication in everyday life. In other words, the audiometer used for hearing tests generates a louder sound at each frequency, then gradually decreases its size so that a minimum decibel that a person can hear the sound is recorded in the hearing degree and based on the recorded hearing level, Of the hearing.

As mentioned above, when hearing loss is more than 25dB, hearing loss is generally reported as hearing loss. According to the statistics of various countries, 2 ~ 4% of the children and 21% of the whole people are reported to have hearing impairment. The more people with hearing impairments get older, the more likely they are to have hearing loss at 81%. It is true that fewer people with hearing loss have various degrees of hearing problems, since hearing loss accounts for about 25% of all otolaryngiopathy patients.

In hearing loss patients, hearing aids such as general hearing aids, implantable hearing aids, and cochlear implants are expected to improve hearing. To understand the effect of hearing aids worn when wearing these devices, Sound field testing is required.

However, the hearing test using a conventional sound field inspection system in a hospital places the speakers in front of the subject in a soundproofing booth at an angle of 45 degrees from the left and right of the subject, and presents a sound (pure tone or note) using a hearing test device outside the soundproofing booth It is a test to see if the subject senses it. As shown in FIGS. 1A to 1C, since the sound field inspection system currently used requires a large loudspeaker to be positioned 1 m ahead of the subject, a large sound booth having a size of 2 x 2 m should be used. However, there is a problem that it can not be used in a small soundproofing booth which is currently used by many otolaryngologists.

In addition, the height of the ears varies depending on the height of the ears according to the patient's sitting height. In the case of a speaker fixed at 1 m in front of the subject, the sound can not be properly transmitted from the ear height of the subject, There was a problem that the comprehension level of the speech was relatively low.

Therefore, there is a need to develop a new structure of a sound field inspection system that can solve the problems of existing sound field inspection systems.

In one embodiment, the vertical unit 110 may be composed of one or two plate-shaped long members and guide members that are partially or wholly installed in the plate-shaped long members. When the vertical unit 110 includes one plate-shaped long member, a plate-like length member included in the vertical unit 110 is disposed on the center side of the wall surface installed as shown in FIG. 2A, When the vertical unit 110 includes two plate-like length members, the vertical unit 110 is installed to be movable along the guide member included in the vertical unit 110. In the case where the vertical unit 110 includes two plate- The vertical unit 110 can be configured to have a plate-like length member and to be fixed to both rear end sides of the lateral unit 120 and to be movably coupled along two guide members included in the vertical unit 110 . Here, the width of the plate-shaped long member constituting the vertical unit 110 is determined by the width of the horizontal unit 120 fixed to the front surface of the vertical unit 110 while the vertical unit 110 is fixed to the wall surface, Can be appropriately determined within a range in which the weight of the unit 130 and the speaker unit 140 can be supported. For example, if the length of the plate-shaped member is one, the width of the member may be wide when the two members are formed.

The guide member may be integrally formed with the plate-like elongated member constituting the longitudinal unit 110, but may be separately formed and attached to the front surface of the plate-shaped elongated member.

The transverse unit 120 is a component that is fixedly installed on the front surface of the vertical unit 110 so as to be movable along the vertical unit 110 with a certain length in the x axis direction and includes a vertical unit 110 One or two coupling portions with the vertical unit 110 may be formed depending on the number of the plate-like length members.
