چکیده
Today, one of the criteria for choosing a vehicle is the comfort inside the cabin, which is influenced by various factors, including the noise inside the vehicle. For this purpose, this research investigates this issue experimentally by choosing a vehicle as a test study and using a portable sound pressure level measuring device. In the first stage, the standard insulators installed on the vehicle are evaluated. In the second stage, the standard insulators are separated from the vehicle and examined without insulation. In the last stage, the vehicle's insulation material is changed, insulation is re-evaluated by installing the new sound insulation, and the desired insulation performance is tested. For all the mentioned stages, two general tests are considered. First, the vehicle is tested under static tests at different engine speeds, including idling speed, 2000 and 3000 rpm, and then the vehicle is tested under dynamic tests at speeds of 30, 50, 70, and 100 km/h. The static test shows the performance of insulation in reducing engine noise, and the dynamic test shows the performance of insulation in reducing road and wind noise. The results indicate that vehicle insulation with Nano polyester significantly affects sound penetration into the interior of the vehicle, which on average is between 5.3% to 8.03% dB in the complete insulation of the vehicle decreases. These findings highlight the effectiveness of nano polyester insulation in improving acoustic comfort inside the vehicle cabin.
