Abstract:

An experimental acoustic survey was conducted inside two fiberglas missile nose cones in a simulated noise field at two intensities and two distances from the noise source. Data indicated an effect of geometric shape on spectral distribution and internal standing waves near the forward part of the nose cone. Empirical methods of computing transmission loss through the nose cone were unsatisfactory for determining sound levels within the nose cone. Author
