Description

  The present invention relates to a method for displaying the performance of blocking floor impact sound generated indoors.

  In Japan, the Housing Quality Assurance Promotion Act (hereinafter referred to as the “Quality Accuracy Act”) was implemented in April 2000, and the Quality Accuracy Performance Display System started in October. The residential performance display system provides consumers with common measures to show the performance of the home to consumers, such as strength against earthquakes and typhoons, safety in case of fire, moisture prevention, antiseptic, and ant protection In addition to measures against deterioration of buildings, the sound environment includes noise blocking performance.

Conventionally, the sound insulation performance against noise can be experienced by a simulation system as described in Patent Document 1. This sound insulation performance simulation system records various types of noise and attenuation data for each specification of the target part such as a wall or ceiling in an external storage device, and makes it possible to recall this noise and data for reproduction by attenuating the noise. This makes it possible to experience the noise transmitted through the target part. Thus, the sound insulation performance against noise is determined by the specifications of the target parts such as walls and ceilings.
JP 7-218329 A

  However, the simulation system as described in Patent Document 1 cannot be experienced unless it is installed in a specific place such as a house exhibition hall, and the customer has to go to such an exhibition hall. There was a problem. In addition, the floor impact sound insulation performance is basically determined by the floor structure of the room and the floor finishing material, similar to the sound insulation performance described in Patent Document 1 determined by the specifications of the target parts such as walls and ceilings. Depends greatly on the floor area of the room. Changing the floor structure and floor finish material of all rooms to the same performance value is the fall of the main customer, and if the performance value is displayed for each floor area of the room, it takes time and effort to get the performance value There is a problem that it is inaccurate when the performance value in some rooms is displayed as the performance of the building. In addition, when the movable partition is moved, there is a problem that the performance of the performance display becomes inaccurate because it is worse than the floor impact sound blocking performance initially presented.

  The subject of this invention is providing the interruption | blocking performance display method of the floor impact sound which can be correctly displayed based on the product quality method.

  According to the first aspect of the present invention, the floor impact sound blocking performance obtained by capturing the floor impact sound generated in the measurement plan room below the floor is displayed as the floor impact sound blocking performance in the building plan room. A sound blocking performance display method, wherein the measurement plan room is composed of the same floor structure and the same floor material as the plan room of the building, and is a large space that is not partitioned other than movable partitions, and the floor of the measurement plan room Even if it exceeds the floor area of the plan room of the building, it is in a range up to 1.3 times.

  The measurement plan room may be a large room with no movable partitions in the building room provided to the customer, or a large space with no movable partitions in a building that is almost the same as the building provided to the customer. The room may be the measurement plan room. Even if the room provided to the customer is a large space without movable partitioning, it can be used as a measurement plan room if it has a floor area more than one third of the floor area of the room provided to this customer. .

  The plan room is a room that is planned to be provided to the customer, and it may be a large space without movable partitions, or it may be a room smaller than the measurement plan room without movable partitions, and it is partitioned by movable partitions. It may be in each room. The rooms partitioned by the movable partition may have different sizes.

  The movable partition partitions a large space room to form a small space room, such as a movable wall. A movable storage partition that also serves as a storage device may be used. These may be provided separately from the provision of the building, or may be initially provided with no movable partition, and the movable partition may be attached to a large space room at a later date to form a small space room.

  According to a second aspect of the present invention, in the floor impact sound cutoff performance display method according to the first aspect, the floor impact noise cutoff performance is displayed as a heavy floor impact sound and a lightweight floor impact noise cutoff performance. And

  According to the floor impact sound blocking performance display method of the first aspect of the present invention, the measurement plan room is composed of the same floor structure and the same floor material as the plan room of the building, and is a large space that is not partitioned other than movable partitions. Therefore, the room partitioned by the movable partition is better than the floor impact sound blocking performance in a large space even if the arrangement of the movable partition is changed. Therefore, there is no performance that is worse than the performance in the measurement plan room, which is a large space, so even if it is displayed as a floor impact sound cutoff performance, it will not be inaccurate without satisfying the display performance, and the floor impact sound It is possible to eliminate the influence of the floor area on the barrier performance. And the floor area of the measurement plan room is in the range of up to 1.3 times even if it exceeds the floor area of the plan room of the building. The above display method is based on the quality assurance method. As a result, it is sufficient to display only one floor impact sound cutoff performance for each building specification.

  According to the second aspect of the present invention, since the floor impact sound blocking performance is indicated by the heavy floor lightweight sound and light floor impact noise blocking performance, it can be displayed more accurately.
