Soundproofing around floating shelves?


Active Member
Hello everyone,

I have a problem with everyday living noises (telephone calls, tv, cupboard doors shutting, etc.) coming through the party wall to our house. In both downstairs rooms we have fireplaces with alcoves either side, which is where the sound seems to be coming through. Now, we don't have room for a stud wall in the alcoves, but resilience bars with soundproofing board is definitely an option.

But here's my problem - in 3 of the alcoves, we have custom built floating shelves that are attached to the wall by a timber frame. The shelves fit the full width and depth of the alcoves. We are selling the house next year, so I don't really want to replace the shelving unless I absolutely have to as it will prove expensive.

So what I am wondering is - would it be possible to apply the resilience bars and soundproofing boards to the party wall between the shelves? (There are only 4 shelves, two close together, two with large spaces between them). Would that still reduce the sound significantly? The only spaces on the wall would then be taken up by the MDF/Wood panels that support the shelves and I heard that sound doesn't go through MDF that well.

I can't do anything with the fireplace, but it is double-brick so hopefully any sound through there will be muted anyway. The sound at the moment is definitely coming through the alcoves.

Any advice would be much appreciated.
