We have recently been a lot of good things about the Genie Clip system. This is a new product in the UK. Designed in Canada it is a product that competes with resilient bars. From the look of them they feel like they should be very effective. Rather than relying on the springy nature of corrugated metal as used by resilient bars, the system relies on a rubber washer to keep metal components apart from each other. The manufacturers claim substantial improvements across the noise frequency spectrum particularly at lower, more tricky to deal with, frequencies. The system that works with a bespoke “furring Strip” is less mistake prone when doing a soundproofing job.
