Reasons to Soundproof Your Car
There are several compelling reasons why you may want to soundproof your car. One of the main reasons is to reduce road noise and increase comfort. The constant droning of the engine, tires, wind, and other vehicles can become tiresome during long drives. Acoustic Foam helps create a quieter, more relaxing environment in your vehicle.
It also helps improve your audio listening experience. With less external noise bleeding into the cabin, you’ll hear subtle details in your music more clearly.
Soundproofing is beneficial for reducing noise pollution for other drivers as well. The honking and loud music from some vehicles can distract and annoy other drivers on the road. Reducing noise keeps your vehicle from being a disturbance.
In some jurisdictions, soundproofing may be necessary to meet legal noise level requirements. Certain vehicles are subject to maximum decibel level limits, especially for modified cars with aftermarket parts like new exhaust systems. Proper soundproofing can help muffle noise to pass inspection.
Excessive noise levels in a vehicle put continuous stress on the body in several ways. Loud low-frequency rumbles and vibrations from the engine, tires, and road surface cause physical tension that accumulates over time.
Prolonged exposure to noises over 85 decibels is considered unhealthy by the World Health Organization as it can lead to elevated blood pressure and heart rate.
Noise disruption also negatively impacts cognitive performance. The distracting din of constant overwhelming sound makes it difficult to concentrate on tasks like navigation, talking on the phone, or having a conversation with passengers. This unnecessary mental strain can elevate stress hormones like cortisol and adrenaline.
Perhaps most importantly, Sound Deadening provides valuable peace and quiet that allows drivers and passengers to more fully relax and recharge during commutes.
Lack of downtime to unwind from daily demands is linked to increased risk of burnout. Muffling sound envelops occupants in a sense of calm that’s conducive to restoring depleted energy levels.
Comfort is also enhanced practically through soundproofing. Passengers can communicate normally without shouting over each other and external disturbances.
Music, audiobooks, and podcasts become much more enjoyable to focus on rather than a boring means to drown out din. Ride quality feels noticeably smoother on highways as concrete isn’t heard grinding under tires.
There are a few other noteworthy benefits to soundproofing your vehicle:
Increased resale value – Cars that have been properly soundproofed will typically command a higher selling price since buyers recognize the value it adds to comfort and user experience. This can help recoup some of the upfront cost.
Performance gains – In some cases, strategic soundproofing can enhance certain aspects of performance. For example, Dynamat or similar products applied to the firewall and floor pans stiffen the chassis and increases responsiveness by reducing interior panel vibrations.
Prevent hearing damage – Prolonged exposure to sounds over 85 decibels can cause permanent hearing loss over time. Heavy bass from large audio systems or loud engines demand soundproofing protection for the health of both drivers and passengers.
Brand loyalty – Automakers recognize the importance of a serene driving experience and noise isolation. Luxury brands especially cater to this through comprehensive factory soundproofing measures. Aftermarket enhancements allow owners of other vehicles to achieve a similar elevated feel.
Enhance audio setup – With less environmental noise interference, car stereos and speaker systems can be calibrated for optimal sound quality. Bass pressure and high frequency definition come through crystal clear.
Here are some more useful tips for soundproofing your car:
Prioritize door kits – Weatherstripping and Dynamat on doors provide an immediate return since they are a major noise point. Kits make the process simple and optimized.
Layer for best results – Adding polyester insulation, foam, or tar paper behind Dynamat creates a stronger noise barrier. The mass stops more vibrations from entering.
Seal every opening – Use foam sealant around windows, vents, wiring holes, etc to block noise transmission paths thoroughly. Tape seams if needed.
Damplifier Pro and ProKit alternatives – These products apply like peel-and-stick sound deadening but are thicker for superior noise blocking in less time.
Trunk kits – Specifically designed trunk weatherstripping and dynamat kits eliminate booming from the cargo area interfering with music.
Cooling/electric fans – Adding soundproofing foam around these units and under shrouds significantly reduces buzzing and drone.
Tires Matter – Thicker sidewalls, softer compounds, and proper inflation all lessen noise transmitted to the cabin from road contact patches.
Stiffer bushings – Mounts that isolate unwanted vibration help stop noise from entering through the suspension and firewall.
Absorbers in strategic areas – Closed cell foam in key trouble zones further eliminates resonances beyond damping sheets.
