Vibration damping

[Johan Bornman]

I have a vibration problem that's proving to be more difficult to solve than I thought.

 

My indoor trainer is in the study above the bedroom.

 

I get up early to ride the trainer and of course, this creates ructions in the household since others still want to sleep. The sound transmits through the floor. I've put a rubber mat under the trainer with no effect. I placed a closed cell foam backpacker's mattress under the rubber mat. No effect.

 

Any vibration consultants out there with a plan?

we use a type of cork vibration pads under our machines.

give me a size and i will cut you a piece to try

JB, does your tyre have a tread? I know the special yellow Conti trainer tyres are super smooth.

Thanks Conti

 

The entire thing stands on a rectangle of 500mm by 1500mm but that's a huge piece. I could get away with two blocks of 500 x 500 and 500 x 200mm.

 

 

Thanks for the offer.

No thread, it's a smooth as glass Continental Supersport Ultra.

 

[Conti]

Sorry Johan

can't help you with those sizes.

we use blocks of 100x100

ditto.  If the floor is vibrating, then a solid floor is needed.  You will not be able to dampen a wooden or "hung" floor

I have some neoprene for you. Will mail you my acoustic consultant's contact details.

Thanks DB. The floor is concrete with slate tiles.

[Dirtbreath]

Sure, I have a pile of wetsuits just in case of emergencies such as these.

[GoLefty!!]

Concrete with slate tiles....theres your problem.

 

 

Neither are particulary vibration damping so you'll need a gel floor mat to stop the vibes getting through the rubber into the floor.

 

What you can try is mounting the legs of the trainer on spikes, similar to those used for supporting hi power speakers like my Mordaunt-Shorts. This will change the frequency of the vibes enough to reduce the problem.

 

What I would consider is fitting a cheap carpet over the floor where you exercise to reduce the noise.

[Johan Bornman]

Thanks Lefty.

 

I've tried the carpet and rubber mat route and soon, thanks to Dirtbreath, a piece of neoprene. Cork and, balsa wood was also suggested.

 

My speakers also came with a set of spikes but I never bothered to fit them. Are they meant to reduce the tansfer of vibrations from speaker to floor? They look ominous. I can't see how I'll spike-mount the trainer so I'll try some of the other remedies first.

 

[GoLefty!!]

They are meant to change the frequency of the vibrations to the floor but also to provide stability to the speaker when standing on carpet.

 I use them anyway on my parque floor because the speaker is then as isolated form the floor as possible. Any vibrations from the casing is thrown in the airspace below with a only 4 tiny channels to direct the vibes straight into the floor. Seems to work well

Where do you buy neoprene. I need some to make fishing reel covers. I have some purpose made ones for the Daiwa Saltega and Exeller but need to make some for the other coffee grinders and Penn type reels. Thickness would be one to two mm Big H2008-09-03 06:08:28
