The noise insulating structure comprises first, second and third sound absorbing materials which are disposed respectively to a head lining, a dash insulator and a floor carpet disposed in the passenger compartment. The first sound absorbing material is capable of absorbing sound within a first frequency range of from 0.8 to 10 KHz. The second sound absorbing material is capable of absorbing sound within a second frequency range of from 0.3 to 2 KHz. The third sound absorbing material is capable of absorbing sound within a third frequency range of from 0.1 to 1 KHz. Each sound absorbing material is formed of a unshaped polyester fiber mixture which is prepared by mixing polyester (main) fibers and binder fibers for bonding the polyester fibers to each other.

Abstract: The invention relates to a sound insulating structure including low-density and high-density layers. The low-density layer has first and second fibrous layers and ranges from 0.5 to 1.5 kg/m.sup.2 in surface density. The first and second fibrous layers are respectively made of first and second thermoplastic synthetic fibers. The first and second fibers respectively have first and second single fiber diameters, each of which diameters is in a range of from 3 to 40 .mu.m, and first and second fiber lengths, each of which lengths is in a range of from 10 to 100 mm. The high-density layer is formed on the low-density layer and is made of an air-impermeable polymer material and has a surface density that is higher than that of the low-density layer and ranges from 1 to 10 kg/m.sup.2. The low-density layer is high in sound-absorption coefficient and at the same time low in spring constant. Therefore, the sound insulating structure becomes substantially improved in sound insulating capability.

Abstract: A sound absorption structure which is mainly applied to an intake system of an automotive engine for suppressing noise level. The sound absorption structure comprises a base duct portion, and an extended duct portion in which a sound absorption material is installed, and a Helmholtz resonator. The extended duct portion is formed such that a representative diameter of the extended duct portion is greater than that of the base duct portion while connected to the base duct portion. The Helmholtz resonator is set to be resonant at a frequency corresponding to a frequency range of a resonance generated by the installation of the extended duct portion including the sound absorption material. The Helmholtz resonator is integrally formed with the extended duct portion. Therefore, the sound absorption structure ensures an excellent sound absorption ability in the whole frequency range.
