Abstract

The invention discloses a door and window sound insulation performance detection apparatus, comprising a casing, a loudspeaker, an output power adjustable amplifier, a signal generator, a first decibel meter, a second decibel meter and a computer. The casing comprises a sound source chamber, a detection plate and a reception chamber which are connected in sequence. Through the first decibel meter in the sound source chamber and the decibel meter in the reception chamber, the sound intensity of the two chambers can be measured at the same time, readings of the first decibel meter in the sound source chamber and the decibel meter in the reception chamber are subtracted to obtain the sound insulation performance of a to-be-detected building door and window. The detection apparatus is small in occupation space, movable, and convenient to detect. No dimension limit is required for a to-be-detected test piece. The test step is simplified and free from influences of human factors. The measurement result is more precise.

Description

technical field [0001] The invention relates to the technical field of sound insulation detection devices, in particular to a detection device for the sound insulation performance of doors and windows. Background technique [0002] Sound insulation is one of the important functions of building exterior doors and windows. Exterior doors and windows with good sound insulation effect can effectively isolate outdoor noise and create a good environment for people's work, study and rest. Using sound insulation of exterior doors and windows of buildings is the best way to prevent and control noise. Important means. For buildings, the sound insulation performance of doors and windows is worse than that of walls, which is the weak link of building sound insulation. People put forward higher requirements for the sound insulation performance of building doors, windows and other components. Therefore, how to detect and evaluate the sound insulation performance of building doors and wind...
