1. Effectively improve the acoustics of Petrol Car
Noise is the destroyer of music. You cannot enjoy beautiful music in a car surrounded by noise, but the sound insulation of Petrol Car can create a quiet audio-visual environment to enjoy the sound quality of music. On the other hand, the installation defects of speakers and subwoofers on the car body can also be solved through vibration reduction during sound insulation construction.
The speakers are installed on the weaker metal panels of the car body, and when they emit sound, they resonate with the metal panels of the car body. Same-wave resonance and harmonic resonance produce noise, distort the sound quality and reduce the acoustic effect. Similarly, the subwoofer is installed in the trunk of a Petrol Car, but when it emits sound, the weak iron piece in the trunk is easily vibrated by the bass sound energy, and part of the sound energy will be converted into heat energy and consumed.
At the same time, it will also bring about the corresponding knocking sound of the board, polluting the original sound. How to solve the shortcomings of these audio modifications, while solving the noise, fully consider reducing the defects of audio installation during the sound insulation transformation.
2. Sound insulation makes up for the defects of speakers
When upgrading a Volkswagen Car audio, a common practice is to add - for new speakers, speakers are often considered the weak link in the audio quality chain, and the speakers in a Petrol Car need to be mounted on a thin metal panel, which is the door The natural drawbacks of installing speakers leave room for improvements in audio quality. When a speaker produces sound, the speaker's base plate resonates or vibrates, causing distortion. For good acoustics, doorways are not a good place to install speakers.
3. Optimize the audio-visual environment in the car
Why does the sound suddenly become louder when I modify a Volkswagen Car stereo when I suddenly stop on the highway? Because road noise swallows up most of the music within the hearing range; acoustic music within the hearing range, when driving at 100km/h, the noise generated by a Petrol Car allows you to hear music within 2085dB; reducing the noise in the car will make dynamic hearing The range is improved by 3dB, 6dB to 12dB. In fact, reducing noise by 3dB is equivalent to doubling the power of your amplifier.
Based on the above analysis, sound insulation of Petrol Car is a top priority. It can not only reduce road noise and wind noise during driving, but also make the Volkswagen Car a closed box, which is conducive to the use of speakers and optimizes the sound inside the vehicle. audiovisual environment.
