Quick Install Sound Insulation Test Aperture

Quick Install Sound Insulation Test Aperture

In this Blog, we present Ventac’s newly upgraded Sound Insulation Test Aperture which is a simple, quick, and easy-to-use system for indicative Sound Insulation and Reverberation tests.

This system employs an ancillary steel frame, together with clamps, which compresses the edges of a test sample onto the clamping surface of the test aperture, distributing an even pressure-seal around the clamped edges in the process as shown in figure 1. 

Figure 1 – Photos of Ventac’s upgraded Test Aperture. The Receiver-Side (Left) is Clamped onto the Test Aperture Surface Using an Ancillary Steel Frame, and Clamps, which Distributes Even Pressure Sealing Around the Edge. The Sample as Seen from the Source-Side (Right) is then Effectively Sealed onto the Adjoining Steel frame in the Aperture and is free of Noise Flanking.

Figure 1 illustrates a test sample securely clamped in place for a sound source-receiver insulation test. It is imperative to note that this aperture test system allows for the prompt and efficient installation and de-installation of a variety of test specimens including flexible and rigid components. Its usage flexibility also gives an allowance for the testing of a vast range of simple and complex structural components. These components range from basic 950mm x 950mm single-squared samples to multi-component structures like ply/metal sheet coupled frames, and complex beam-coupled structural components, at varying depths and thicknesses of up to 150mm.

The ease of sample installation and efficacy in the elimination of noise flanking around the sealed edges, which mainly characterises this system, allows it to be used in test experiments where repeatability and experimental integrity are key. Due to the relatively small sample size requirement, typical test applications for this system include, but are not limited to, the research and development of vehicle components, building & industrial components, as well as scaled-prototype laboratory testings for the building, construction, and automobile industries.
