CONDICE When You Share a Wall
A licking head is quieter than a motor, and it still carries through a wall at 45 dB.
What CONDICE sounds like through a wall: the frequency a licking motor produces, the settings that keep it slow, and hours that work in a shared building.
The Short Answer
Stay on the first three of nine speeds and put a folded towel under the device. A licking head produces a lower, more rhythmic sound than a vibration motor, and low frequencies pass through drywall with less loss. At about 45 dB on the top speeds, it's noticeable in the next room. At speeds one to three, it drops closer to a hum that a fan or a refrigerator can mask.
What a Licking Motor Sounds Like
It doesn't buzz. It taps. The head moves in strokes, and each stroke is a small mechanical event rather than a continuous tone.
That changes how it travels. A steady tone blends into background noise. A rhythmic tap stands out, because the ear is good at picking patterns out of a hum.
At 45 dB, the device is roughly as loud as a quiet conversation. The difference is that a conversation has words, and this doesn't, so a neighbor notices the pattern before the volume.
Inside the room, the sound is easy to ignore. Through a wall, it's the only thing in the room that repeats.
Low Frequencies Travel
The stroke rate of the head is low, and low frequencies lose less energy at each boundary. That's why a bass line from a neighboring apartment is more intrusive than a television at the same volume.
CONDICE sits in that range. The motor itself is small, and the head's movement produces a thump rather than a whine.
That's also why a white noise machine helps less than people expect. It masks high frequencies well and low ones poorly.
A fan with a low rumble does more than a fan with a hiss. If you're choosing between two, choose the one that sounds like moving air, not like static.
Surface Contact and Structure Noise
The surface the device rests on matters more than the setting does. On a hard nightstand, the body acts as a small speaker.
A folded towel under it decouples the body from the wood, and the difference is audible in the next room. It's the cheapest change available.
Holding it in your hand instead of resting it also helps. Your hand damps the vibration, and the contact area is smaller than a tabletop.
Beds transmit too. A mattress is a large, lightly damped surface, and the frame touches the floor and the wall.
The Best Hours in a Shared Building
The quietest hour in a shared building is not midnight. It's usually 9 to 10 p.m., before the last elevator trips and before the building settles.
At 11 p.m., the ambient noise drops and the device becomes the loudest thing on the floor. At 9:30, a dishwasher or a television two units over is still doing some of the masking.
If your schedule allows it, move the session earlier. The same device at the same setting is far less noticeable at 9:30 than at 12:30.
If it doesn't, accept that the settings have to do more work, and plan for a shorter session.
Settings That Keep the Motor Slow
Speeds one to three keep the stroke rate low. Above five, the head moves fast enough that the taps blur into a continuous sound, which travels differently and further.
Counterintuitively, the fast settings can be less noticeable than the mid ones. A blur reads as a hum. A slow, distinct tap reads as a mechanism.
That's worth testing in your own room rather than assuming. Put the device on a table, walk into the next room, and listen at speeds two, five, and eight.
- Quietest in the next room: speed two, on a towel.
- Least noticeable: speed eight, where the taps blur.
- Most noticeable: speed five, distinct and mid-frequency.
What You Can't Engineer Away
Skip the quiet protocol if the wall is shared with a room that has a gap under the door. At that point, the building is the limitation, and no setting fixes a gap.
Hold off on long sessions if a neighbor has already mentioned noise. One comment changes the social math, and a 30 minute session is not worth a second conversation.
The honest limitation is that 45 dB is quiet, not silent. A licking head on a hard surface in a room with no carpet will still be audible through drywall at night.
And at 2.6 ounces, the device is light enough that it moves when the head runs. A device that walks across a nightstand makes more noise than one that stays put.
Start Quiet, Then Adjust
A towel, speed two, an earlier hour. Adjust from there.
