Is This a Noise Restrictor?

Before I replaced my hand-held shower head with a HammerHead I removed from it what I think is a flow restrictor. I also placed the head past a little valve so I could change the flow. When the valve is fully open, the shower is relatively quiet and as soon as I begin to restrict the flow to the head it gets pretty noisy. If I put the little restrictor back inside the head will the noise go away? Here's a picture of the restrictor (0.6" diameter):

It is a flow restrictor

But does it affect the "rushing" noise from the shower?

It could, the water is moving slower through the restrictor and into the showerhead which could cause it to be quieter than the water moving faster without the restrictor.

So I put the restrictor back in and now I don't have any noise. The flow, while not as much as it was without the restrictor, is still adequate and I'm happy-happy!

On those restrictors I use a pick and remove the o ring but leave the green portion in the shower head
