    Hum, Buzz & Suitability as an Alarm Clock

    This is mainly aimed at the Beta testers I suppose.

    I know that one of the main features of the SBB is it's use as an alarm clock but I was wondering if when you have both the power supply and actual SBB next to your bed can you hear any humming or buzzing at all?

    Thanks

    Note in the audio design document that Dean posted: "Production units have foam around the wires to prevent buzzing."

    This is obviously an area that they've been keen to address and based on my experience with SD, I'm sure an area they've succeeded in.

    No hiss or hum here.

    If you press your ear directly to the speaker grille there's a faint hiss, but I sleep 12-18" away from it with the speaker aimed directly at my left ear and I can't hear it at night - and I'm a light sleeper.

    The power supply is a switching power supply and doesn't make any noise at all.

    This very quiet hiss was discovered just a day or two ago and we'll do
    our best to address it in a future software update.

    There was a LOT of work done to minimize buzz, hum and hiss. I may be
    a bit biased but I think Boom sounds amazing, especially considering
    the price.

    I can confirm what Mark says. I used it 2 feet from my head while sleeping for a while and it never had a hum or buzz. I now keep it across the room from my bed but that is only for ease of accessing a power outlet because I move it around a lot.

    I am a light sleeper, mine is across the room, and neither the sound nor the light bothers me at night. It auto-dims (in case no one mentioned that yet).

    Mine is about 4ft from the bed on a shelf facing me... and I am a VERY light sleeper (usually up most of the night). The VFD gets just dark enough that it doesnt bother me, but is still readable when I wake up. There is zero noise coming from the Boom as far as I can tell.

    Also the alarm fades-on, which is a very nice touch because I can quickly get up and turn it off before it wakes my wife up too much...

    Yes, the auto-dimming is wonderful. I am very fussy about having any light in the room while sleeping and the dimness of the Boom at night is just right. I've replaced my SB2 with the Boom in the bedroom because of the auto-dimming.

    With the outboard switching power supply and the use of digital amps, I have never heard any buzzing or humming from my Boom. They did a great job and knew what type of places folks were going to put them into. I really enjoy using the Boom to get to sleep. Just put some nature tracks on, set the sleep, and drift away. No worry that my Stereo Receiver is on all night like when I used the SB3.

    Gratuitous self-promotion: I think anybody using the sleep mode should check out my SleepFade plugin. I use it frequently with the SN nature sounds to help my toddler go to sleep and ensure the sound fades out more gradually. I can't take credit for the idea (see http://forums.slimdevices.com/showthread.php?t=32664) but I sure do find it handy.

    Oh, and you should look at IR Blaster, Power Switch, and PowerCenter for that stereo receiver!
