Our team is proud to support vehicle manufacturers in reducing automotive noise.
Here at IPS Perforating, Inc., we do more than just punch holes in materials—we help engineer silence for our automotive customers. Perforations are a huge part of automotive noise reduction systems, helping a vehicle feel like a peaceful sanctuary even on a busy highway. If you’re looking for a team that can provide the precision perforating services you need for your automotive company, we’re the ones for the job.
One secret to automotive noise reduction via perforations lies in sound wave absorption. When acoustic energy (sound) encounters a perforated surface, the sound waves enter the perforations and interact with the substrate material behind them. The sound energy is converted to heat as air molecules vibrate within the perforations, and this process prevents the sound from reflecting back into the vehicle cabin.
Another way that perforation helps with automotive noise reduction is by breaking up sound paths. The perforations disrupt the smooth reflection of sound waves, scattering and diffusing them. This reduces their intensity and helps prevent focused sound reflections that could create resonance within the cabin.
There are a number of areas where perforations can aid in automotive noise reduction, including:
- Headliners and roof linings
- Door panels and trim components
- Under-hood insulators
- Floor carpets and trunk liners
- Seat materials
We can engineer the sizing and placement of the perforations to help with specific frequency targets. For example, smaller holes that are spaced closely together often work better for higher frequency sounds, while larger holes often work well for reducing lower frequency sounds.
Our perforation services offer a sophisticated and subtle approach to automotive noise reduction. If you’d like to learn more or are interested in working with our experts, reach out to us today.
