Model Description

4206T type transmitted loss pipe kit (50Hz to 6.4kHz) ■ configuration ・ 2 tubes with 100 mm inner diameter (thick tube) ・ 29 mm of inner diameter (thin tube) 29 mm ・ Sample holder (inner diameter 29 mm and 100 mm) ・ Extension tube (inner diameter 29 mm and 100 mm) ■ Two types of tube configurations can be assembled ・ Thick tube setup for parameter measurement of frequency range from 50 Hz to 1.6 kHz ・ Fine tube setup for parameter measurement of frequency range from 500 Hz to 6.4 kHz The interior of the pipe is attached to the 4206t type, and is performed at the 4187 type 1/4 inch condensed samicrophone, which is specially designed to exclude sound pressure leak errors at high frequencies. ■ Applications Measurement of transparent loss of materials is important in noise control using barriers. For example, in a car, the dashboard plays a role as a soundproof wall between the engine room and the car chamber, or in buildings, the wall or door will interrupt the noise, but separate the noise source and the person. Is important. There is a technology for measuring the performance of the entire component (such as dashboard, door, etc.) using the sound source room, sound reception room, or reverberation room (dashboard, door, etc.). But this measurement takes time to set up and get results. In addition, measurement of the entire component is the material of the component, the geometry (shape) of the component, and the boundary conditions. And the sensitivity to the fixing method is very high. In the following applications, it is desirable to directly measure the transparency of the component material. ・ Various materials comparison in specific applications ・ Analysis model used for design of materials and components ・ Verification of the performance of materials before processing into components The transparent loss pipe kit is useful for directly measuring the transparency of the material.
