Description

TECHNICAL FIELD The present invention relates to a sound absorber and a booth provided with the same.

2. Description of the Related Art Most offices of individual companies or coworking spaces shared by a plurality of companies have booths provided with tables and chairs for work, meetings, etc., as shared spaces. Here, since such booths are often installed adjacent to other booths at a short distance, sound absorption, sound insulation, shielding, and the like are required.

For example, Patent Literature 1 discloses an example of constructing a sound absorbing body in which a large number of sound absorbing bodies are suspended from the ceiling.

Japanese Utility Model Publication No. 7-46643 (Fig. 3)

By the way, in Patent Document 1, since the sound absorbing body is suspended near the ceiling of the room, it is not suitable for sound absorption and sound insulation for the booth as described above, and it is difficult to shield the line of sight from the surroundings. .

The present invention has been made in view of this point, and its purpose is to install it in an existing booth to suppress the echo of sound in the booth, reduce sound leakage, and shield the line of sight. That's what it is.

To achieve the above object, a sound absorbing body according to the present invention includes a sound absorbing body suspended from the ceiling of a room in which a booth is provided on the floor, and the sound absorbing body partitions the booth. It is characterized by being provided as follows.

According to the above configuration, the main body of the sound absorbing body is suspended from the ceiling in the room, so it can be installed using the ceiling above the existing booth. In addition, since the sound absorber main body is provided so as to partition the booth provided on the floor surface, the sound inside and outside the booth is absorbed by the sound absorber main body, suppressing the reverberation of the sound inside the booth. As a result, it is possible to improve the easiness of conversation within the booth and reduce sound leakage to the inside and outside of the booth. Furthermore, since the main body of the sound absorbing body serves as a blindfold, it is possible to shield the line of sight from the surroundings. Therefore, it can be installed in an existing booth to suppress the reverberation of sound in the booth, reduce sound leakage, and shield the line of sight.

The sound absorber main body may be provided so as to surround the booth.

According to the above configuration, since the sound absorbing body is provided so as to surround the booth, the sound that travels from inside the booth and the sound that travels from four directions around the booth to the booth is absorbed by the sound absorbing body, It is possible to reduce sound leakage to the inside and outside of the. Furthermore, by absorbing sound traveling in all directions from inside the booth into the main body of the sound absorbing body, it is possible to suppress the reverberation of the sound inside the booth and improve the easiness of conversation inside the booth.

The sound absorber main body may be provided with an entrance through which a person using the booth enters and exits.

According to the above configuration, since the doorway through which the person using the booth enters and exits is provided in the main body of the sound absorbing body, it is possible to easily enter and leave the booth.

The sound absorber main body may be provided so as to penetrate in the height direction.

According to the above configuration, since the sound absorbing body is provided so as to penetrate in the height direction, light can be taken into the interior of the booth from the lighting provided on the existing ceiling, and the feeling of blockage and oppression can be eliminated. This reduces the feeling of discomfort and improves the comfort inside the booth.

A pair of the sound absorbing bodies may be provided so as to face each other with the booth interposed therebetween.

According to the above configuration, since a pair of sound absorbing body bodies are provided so as to face each other across the booth, sound directed in two directions (front and back or left and right) from inside the booth and two directions around the booth (front and back) or left and right) is absorbed by the main body of the sound absorbing body, and sound leakage to the inside and outside of the booth can be reduced. Furthermore, by absorbing sound traveling in two directions (back and forth or left and right) from inside the booth, the reverberation of the sound inside the booth is suppressed and the ease of conversation inside the booth is improved. can be done.

The sound absorbing main body may be provided so as to move up and down in the height direction.

According to the above configuration, since the sound absorbing body is provided so as to move up and down in the height direction, when the booth is used as a private space, the booth can be partitioned by lowering the sound absorbing body, When the booth is not used as a private space, the booth can be used as a public space by raising the sound absorbing body.

A booth according to the present invention is characterized by including the sound absorbing body described above.

According to the above configuration, in the sound absorber, the main body of the sound absorber is suspended from the ceiling in the room, so the sound absorber can be installed using the ceiling above the booth. In the sound absorbing body, since the sound absorbing body is provided so as to partition the booth provided on the floor surface, the sound inside and outside the booth is absorbed by the sound absorbing body, thereby reducing the noise in the booth. Resonance can be suppressed to improve ease of conversation in the booth, and sound leakage to the inside and outside of the booth can be reduced. Furthermore, since the main body of the sound absorbing body serves as a blindfold, it is possible to shield the line of sight from the surroundings.

According to the present invention, since the sound absorbing body is provided so as to partition the booth, it can be installed in an existing booth to suppress the echo of sound in the booth, reduce sound leakage, and shield the line of sight. be able to.
