Decibels are odd things and though objectively or scientifically easy to measure, they can be confusing. How an individual hears them is not a constant, it is very subjective. An increase of 3dB doubles the sound pressure, and requires 3 times the acoustic power, though perceived doubling in volume takes 5 to 10db depending on the listener.
However we can say that more decibels (tenths of Bells) are louder.
Cutting to the point of this post, we recently had a set of our DubStar feet, the set made for the Technics 1210, tested under probably worst case scenario conditions. Our feet were compared with two other brands and the standard feet in a Dub Reggae type venue by DJ and sound engineer Prince Fatty (Mike) with an array of powerful subwoofers as part of the setup. (I need to go and hear it myself – Fox and Firkin, Lewisham High Street.) Noise control scientist Ray was helping with the experiment. As far as I can ascertain, music was played at increasingly loud volumes until feedback was detected in the turntable stylus.
They conducted the experiment on the different brands and then combined some of the feet.
The Solidair Audio DubStars “reigned supreme” 4dB ahead of the closest and 11dB better than standard feet. Our feet also showed no weakness at a particular frequency, or resonance, which was very pleasing to see.
I think Ray liked the runner up as they cost less, which is fair enough. We always aim to make the best here, with no compromise in materials and craftsmanship. We want to offer the best for every audiophile and their HiFi, so you only need to buy once.
Apparently with our feet combined with the top runner up another 3dB was possible, but at this point they were setting off the car alarms outside the venue!
So it’s official, Solidair Audio DubStars are seriously good turntable isolation feet.
