Nap Alarm – 80dB Over-Ear Drowsiness Alert Device

Fatigue doesn’t announce itself — it closes in gradually until a head-nod or microsleep is already happening. The Nap Alarm mounts over your ear and uses an electronic position sensor to detect that forward tilt the moment it begins, sounding an 80dB alert that cuts through the silence of a quiet cab, office, or study room before the situation escalates.

Who This Drowsiness Alarm Is For

This device is purpose-built for people whose safety depends on sustained alertness. Long-haul and commuter drivers who regularly log miles after a full workday are the primary audience. Night-shift security personnel, machine operators in industrial environments, and overnight caregivers who must drive home exhausted will also find it immediately useful. Students pulling late study sessions round out the picture — anyone who needs a passive, automatic safety net rather than a behavioral trick like coffee or a nap timer.

Nap Alarm: Frequently Asked Questions

How does the Nap Alarm detect drowsiness?

The device uses an electronic position sensor mounted in the over-ear housing. When your head tilts forward past the normal upright angle — the motion that occurs during the earliest stage of nodding off — the sensor registers the change and immediately triggers the 80dB alarm. The process is entirely automatic; no button or gesture is required from the wearer.

How loud is the Nap Alarm’s alert, and will it wake me if I’m deeply drowsy?

The alarm outputs 80dB, comparable to a busy restaurant or a ringing telephone held close to the ear. In the quiet interior of a vehicle or a low-noise workspace, that level is sufficient to startle a drowsy wearer back to full alertness. The alert is designed to trigger at the onset of nodding, before deep sleep sets in.

What batteries does the Nap Alarm use, and are they included?

The Nap Alarm runs on three AG13 alkaline button cells. All three are included in the package, so the device is operational immediately out of the box. Replacement AG13 batteries are a common size sold at most electronics retailers and pharmacies.

Is the Nap Alarm comfortable to wear for a full shift or a long drive?

At 0.06 lbs and measuring 1⅞” × 2¼” × ⅝”, the unit is light enough that most wearers stop noticing it within minutes. The over-ear clip is designed to stay secure without clamping pressure, and the low-profile housing does not conflict with standard eyeglass frames. It is not intended for use with in-ear hearing aids or large over-ear headphones.
