Teacher explaining calculus problem with frequent student verbal affirmations and low background noise.
Multi-party peer dialogue, elevated productive acoustic volume, alternating turns of speech.
Off-topic overlapping whispering, shuffling chairs, teacher speaking over persistent background babble.
Prolonged teacher monologue with zero student questions, flat acoustic energy, low interactive responsiveness.
From Classroom Noise to Formative Clarity
Automated intelligence engineered to integrate seamlessly into active classroom teaching without disruptions.
Capture Ambient Sound
Record a 5–15 second snippet via browser microphone, drop an audio/video file, or select a pre-calibrated instructional scenario.
- Zero hardware setup required
- Web Audio HTML5 decibel extraction
Dual-Engine Neural Inference
Whisper models isolate speech cadence and noise floors, while Gemini 2.0 Flash infers classroom-wide dialogic engagement ratios.
- Fast 2.8s turnaround time
- Acoustic calibration to room decibels
Deploy Formative Interventions
Review your 0–100 Focus Index and immediately implement 3 targeted pedagogical tactics (Think-Pair-Share, pacing adjustment, quiet resets).
- Actionable in under 1 minute
- REQ-007 reflective pedagogical focus
Engineered Specifically for Educators & Coaches
Designed to address the real acoustic dynamics of modern teaching, from direct instruction lectures to collaborative small-group sessions.
Acoustic Decibel Telemetry
Measures continuous room decibel levels to distinguish productive collaborative discussions (50–65 dB) from overwhelming classroom chatter (>72 dB).
Teacher vs. Student Talk Ratio
Provides real-time visibility into conversational turn-taking, ensuring lessons maintain a healthy active-learning dialogic balance.
Actionable Coaching Interventions
Generates 3 immediate pedagogical reset prompts per analysis, helping instructors adjust lesson pacing and re-engage back-row learners instantly.
Zero Biometric Storage
Strict compliance with FERPA and COPPA standards. No facial recognition vectors, no voiceprints, and automated 24-hour non-persistent ephemeral purging.
Continuous Live Audio Gauge
Keep the dedicated Web Audio decibel meter running on your tablet or podium display with color-coded alerts when volume exceeds guidance levels.
Sensifai Native Integration
Single sign-on via Logto OIDC, automated prepaid wallet credit deduction (€0.05 / request), and comprehensive REST developer endpoints.
Live Acoustic Energy Gauge for Your Classroom
Open the dedicated live audio monitor on your teacher tablet or interactive smartboard. Track decibel levels in real time, visualize classroom sound dynamics, and maintain productive collaborative volume.
How Classroom Focus Meter Compares
Objective telemetry that empowers teachers without the disruption of walkthroughs or privacy violations of wearable trackers.
| Evaluation Dimension | Classroom Focus Meter | Admin Walkthroughs | Wearables / Eye-Trackers |
|---|---|---|---|
| Feedback Latency | Under 3.9 Seconds | Days to Weeks | End of Day Sync |
| Student Privacy (FERPA) | 100% Zero Biometrics | High Privacy | Severe Risk (COPPA Violations) |
| Classroom Disruption | Zero (Non-Intrusive) | Observer Alters Dynamics | High (Devices on Students) |
| Pedagogical Guidance | 3 Instant Reset Tactics | Subjective & Generic | Raw Raw Heart/Eye Data |
| Cost Model | €0.05 / Session (Pay-As-You-Go) | High Staff Cost | €5,000+ Hardware Bundles |
Ethics, Privacy & Regulatory Compliance
REQ-007 Formative Guarantee
Classroom Focus Meter is strictly engineered for formative pedagogical reflection. It does not provide clinical diagnoses, disciplinary records, or evaluative personnel ratings.
FERPA & COPPA Aligned
Student identities are safeguarded with zero persistent facial geometry, zero biometric templates, and zero audio storage.
24-Hour Non-Persistent Purge
Temporary telemetry artifacts are purged automatically. All metrics remain anonymous and private to the educator session.
