Great question! The RV series of aircraft have always been admired for their performance and efficiency. When it comes to soundproofing in an aircraft, it’s a unique challenge, different from vehicles, yet there are parallels. I’ve had personal experience soundproofing cars with products from sound deadening , and the effectiveness of specialized materials in reducing noise can be significant. That said, in an aircraft, weight is a paramount consideration. While soundproofing can make the cabin environment more pleasant, especially during longer flights, it’s a balance between the benefits of a quieter environment and the performance implications of added weight. ANR headsets indeed do an excellent job of noise cancellation, and for many, that’s sufficient.
