When you get settled behind the wheel of your new car for the first time, one of the top priorities is hitting the road and cranking up the music. For many, the vision of cruising down the roadway with tunes playing and a sense of total freedom is a big influence on what type of new or used vehicle they purchase. After a few hours or a few days of musical bliss, you become aware that there is interference with the sounds. Road vibration and the tiny movements of the car’s structural system create an environment where the sound becomes distorted. No matter how you fuss with the car audio wiring, the bass sounds muffled and the upper ranges flutter or are overwhelmed by the sound of the road.
Dynamat products provide sound deadening that suppresses the vibrations and acoustic distortion that reduces enjoyment from your sound system. The sound deadener comes in several configurations for easy application in your vehicle. The acoustic foam has self-adhesive backing to make it easy to work around the car audio wire and the mechanical features. You can get a package to specifically treat the metal areas that reverberate and the larger open spaces — like the trunk — where sound echoes and builds.
An initial installation of sound deadener should be around the speaker box to promptly cut down on the movement of the metal that causes under-performance and poor sound quality. Sticking the deadener onto the metal surrounding a speaker creates a rigid surface that significantly reduces the vibration. The work may be done with a standard sound deadening product designed specifically for the application or with an upgraded version that is costs a nominally higher price but adds extra rigidity and has extra sound aborbing properties. The result will be immediately audible when you take the vehicle for a music-filled spin.
It’s your choice which area of the vehicle to treat with sound deadener next. You will probably have a good feel for which areas are most problematic after you have driven the car for about a week or two. Many choose to apply the deadening material to the doors next. This process can be done as a do-it-yourself project. If you don’t have the tools or level of confidence to remove the factory-installed door panel, get an experienced friend or a car audio wire dealer to do the job for you. The material, once installed, functions like a barrier to block outside sounds from entering the car. The external noise quotient is reduced by several decibels — sufficient to enhance your listening experience quite noticeably.
By the time you have installed sound deadener around the speakers and in the doors you may have started to notice that the bass your system produces may sound muddy and muffled. Bass sound waves have a longer frequency than the rest of the audible range; many car passengers comment that they can hear the bass better just outside the car than after they get inside. To address this acoustic problem, deadening is applied to the interior of the vehicle’s trunk. This area is typically treated with thicker dynamat acoustic foam to absorb excess sound waves. At the same time, the foam holds tightly to reduce the rattles and quirky little noises that occur in the vehicle’s back end.
Now you are able to enjoy the crisp, clear sounds of a great audio system whenever you are in the vehicle. You may be surprised to find that the vehicle interior is more comfortable when you have the sounds turned down, too. When the vibration and structural noise is under control, it is less fatiguing to carry on a conversation with passengers.
