摘要： A sound insulator of the invention includes a sound absorption layer 202 and an air-impermeable resonance layer 203, which are bonded to each other via an adhesive layer 204. The sound absorption layer 202 has a thickness in a range of 5 to 50 mm and an area-weight of not greater than 2000 g/m2. The sound absorption layer 202 has a two-layer structure of a high-density sound absorption layer 202a and a low-density sound absorption layer 202b, which have different densities. The high-density sound absorption layer 202a is bonded to the air-impermeable resonance layer 203 via the adhesive layer 204 and has a density in a range of 0.05 to 0.20 g/cm3 and a thickness in a range of 2 to 30 mm. The low-density sound absorption layer 202b is bonded to the other face of the high-density sound absorption layer 202a, which is opposite to the air-impermeable resonance layer 203, via an adhesive layer 202c and has a density in a range of 0.01 to 0.10 g/cm3 and a thickness in a range of 2 to 30 mm. The structure of this sound insulator effectively reduces a noise level in a voice-tone frequency band, especially in a high frequency domain, thereby efficiently enhancing the clarity of conversion in a vehicle interior.

摘要： The objective of the present invention is to efficiently and inexpensively mass-produce a sound insulator for a vehicle which is light in weight and has excellent sound insulating properties. For this purpose, the ultra-light sound insulator of the present invention is composed of a felt single sheet 3 having a vehicle interior side surface 1 and a vehicle exterior side surface 2 and being thermoformed of cotton fibers and binder fibers which are tangled and contacted and jointed to each other in a random manner. The ratio of the stiffness of the vehicle interior side surface 1 to that of the vehicle exterior side surface 2 is set to be in a range of 1.1 to 10. The single sheet 3 also has an area of gradually-decreasing stiffness 4 that spreads over at least one part of the area between the vehicle interior side surface 1 and the vehicle exterior side surface 2. The area of gradually-decreasing stiffness 4 has a stiffness distribution pattern in which the stiffness decreases gradually from the vehicle interior side surface 1 toward the vehicle exterior side surface 2 with respect to the direction perpendicular to the vehicle exterior side surface 2.
