Resumen de Pressure and vibration airborne two-ways sound insulation ratings comparison
Roberto San Millán Castillo, Javier de Luis José, Rebeca Goya Esteban, Eduardo Morgado Reyes
When dealing with several sound insulation ratings, results are quite different as they depend on algorithm variables. Dn, DnT, and R´ values do not converge usually although they are all transmission lost estimators. Firstly, it is assessed how new ISO 16283-1 standard influences the difference among ratings versus previous ISO 140-4, when testing both possible ways at a University classroom. Besides, those pressure procedures are compared with one based on vibration measurements, Solidnoise™. Both methods are analysed and a more sustainable use proposal is suggested.
