Prediction model for the impact sound level of lightweight floors
(2003) In Acta Acustica united with Acustica 89(2). p.309-322- Abstract
- Lightweight floors are often troubled by poor impact-sound insulation. In order to develop and explain structures with acceptable insulation, a deterministic prediction model was developed. The paper considers transmission through the system and the response of the model. Excitation (as caused by the ISO-tapping machine) is considered in a separate paper [1]. The system description employs a spatial transform technique, making use of the periodicity of the floor structure with the aid of Poisson's sum rule. The radiated power is calculated using numerical integration in the wave-number domain, the radiated power enabling the impact sound level to be calculated. Comparisons are made between measurements found in the literature and the... (More)

A relatively close agreement is achieved, especially if an elaborate excitation model is employed. (Less)
