Should be amenable to sound cancellation -small speaker and microphone near scanner with a negative feedback amplifier...

    Hi Confocalists,
   
    We’re trying to circumvent the annoyance of resonant mirrors screaming at 8 kHz. I was wondering whether anyone has a recommendation for constructing soundproof containment?
   
    Generally were using inexpensive resonant mirrors from EOPC: http://www.eopc.com/sc30.html
   
    Also, does anyone know whether the more costly resonant scanners used for confocal/multi-photon laser scanning microscopies are any better in this regard? Were not hugely concerned with other attributes (simply for light sheet microscopy stripe suppression) just the piercing noise.
   
    Many thanks in advance!
   
    Rory
