Abstract

PURPOSE:To improve architecturally and structurally acoustic characteristic under balcony seats of a hall equipped with the balcony seats such as multi-floor seats exceeding second floor seats. CONSTITUTION:In a hall 1 having seats 4 upward of seats 3, an acoustic opening 9 connecting an upper space of the seats 4 to an upper space of the lower seats is provided backward of the upper seats. The acoustic opening 9 is provided backward of the upper seats 4 except an aisle part 11. Accordingly, sounds of a stage are circulated around rear seats downward through the acoustic opening, and acoustic characteristic in the rear seats can be architecturally promoted.

According to the present invention, in order to achieve the above-mentioned object, in a hall in which passenger seats are provided above the passenger seats, a space above the passenger seats is provided below the passenger seats above the seats. There was an acoustic opening that communicated with the upper space of the seats. It is preferable that the acoustic opening is formed large in the rear of the upper passenger seat except for the passage portion.

[Function] Sound generated on the stage is reflected by the ceiling, floor surface, side walls, and acoustic reflectors at the back to reach the audience seats. Since the reflected sound from the upper floor enters through the opening,
The lack of sound arrival due to the presence of the balcony seats above is compensated for, and the acoustic characteristics are improved.

Embodiments of the present invention will be described with reference to the drawings.
In FIG. 1, reference numeral 1 is a hall provided with a stage 2 having an open ceiling, and a second-floor passenger seat 4 is provided as a balcony passenger seat above the first-floor passenger seat 3, and an acoustic reflector 5 is provided on the ceiling. Reference numeral 6 is an acoustic reflector provided on the stage 2 during a concert.

Although such a structure is not particularly different from the structure of the conventional hall, in the case of the present invention, the space 7 above the second-floor passenger seat 4 is located behind the second-floor passenger seat 4 which is the upper passenger seat.
An acoustic opening 9 communicating with the upper space 8 of the floor seat 3 is provided.
The acoustic opening 9 is placed under the passenger seat 4 on the second floor to the passenger seat with poor acoustic characteristics.
The sound from the stage 2 is reflected by the rear wall 10 and the like and wraps around the sound source, and the acoustic characteristics there are improved.

The improvement of the acoustic characteristics mentioned here means the improvement of each element of reverberation time, sound pressure distribution, and acoustic evaluation index.
The acoustic evaluation index is an echo time pattern, direct sound component to total energy ratio (D value), Clarity C (C value), and time center of gravity ts. When the acoustic opening 9 is not provided, the reverberation time of the rear seat A of the first-floor passenger seat 3 is about 3 seconds when the sound source of the stage 2 is 1 KHz. 5 to 10% less than that. In addition, the sound pressure distribution is compared with the case without the acoustic opening 9 and
As shown in FIG. 4, the sound pressure is increased when the acoustic opening 9 is provided, and the sound pressure of the sound of 500 Hz is significantly increased rather than the sound of 1 KHz. The sound pressure did not change in the first-floor seats 3 near the stage 2. Further, the echo time pattern of the acoustic evaluation index has a large amplitude for a long time in a sound source of 1 KHz and 1 octave, and the echo effect is good. The D value is smaller in the case where the acoustic opening 9 is provided than in the case where it is not provided, as shown in FIG. 6, and the C value indicating the intelligibility of the sound is also decreased as shown in FIG. The center of gravity ts becomes large as shown in FIG. 8, and it can be seen from these indexes that the diffuse sound component is increasing. When the depth of the second-floor passenger seats 4 becomes deeper and the area covered by the second-floor passenger seats 4 of the first-floor passenger seats 3 becomes larger, the acoustic characteristics of the covered passenger seats further deteriorate. By providing it, the acoustic characteristics can be improved.
As shown in FIG. 3, it is preferable that the acoustic opening 9 is formed to be large behind the passenger seat 4 on the second floor except for the passage portion 11.

As described above, according to the present invention, since the acoustic opening that communicates the upper space with the upper space of the lower passenger seat is provided behind the passenger seat above the hall, the acoustic opening is provided. Through this, the sound of the stage wraps around to the lower back passenger seats, and the acoustic characteristics of the rear passenger seats can be architecturally improved, which is advantageous for concerts.
