Vocala vs Noise Shield

Vocala shows a room how loud it is — and helps it get quieter. Put it on the projector during class, on the table during a meeting, or next to a sleeping baby. Vocala measures the sound level in real time, changes colour as the room gets louder, and gives a gentle alert when it crosses the limit you set. LEVELS ONLY. NOTHING IS RECORDED. Vocala measures decibels, not words. No audio is ever stored, sent or analysed. Nothing leaves the device. CLASSROOM MODE • A big, friendly face that reacts to the room — readable from the back row • Quiet points and quiet streaks the whole class earns together • Presets for silent work, group work, transitions and nap time • A new-record banner when the class beats its best MEETINGS • A calm meter on the table that keeps one voice at a time • Lock the phone — the level stays on the Lock Screen and in the Dynamic Island • A summary when you stop: how much of the meeting stayed under the limit EVERY SESSION ENDS WITH A VERDICT Average, peak, time over the limit, longest quiet streak and a chart of the whole session. Keep your last sessions free; Pro keeps them all. WEEKLY REPORT See the week at a glance — quiet share per day, best session, total points — and share it with parents, colleagues or your head of department. VOCALA PRO • Unlimited session history and charts • Classroom mode without time limits • Export sessions as CSV or image, share weekly reports • All presets, 9 visual themes and custom alert tones Try Pro free for 7 days, then yearly or monthly — or pay once for lifetime access.

NoiseShield is your personal sound safety assistant. It continuously monitors ambient noise in your environment using your device’s microphone and alerts you when sound levels reach dangerous thresholds. Whether you're in a city, a concert hall, a factory, or even at home using TV, NoiseShield helps you make informed choices to protect your hearing—before it’s too late. Why NoiseShield Matters Hearing loss caused by noise exposure is entirely preventable, yet it affects millions of people globally. According to the Centers for Disease Control and Prevention (CDC): “Noise above 70 dB over a prolonged period may start to damage your hearing. Sound at or above 120 dB can cause immediate harm.” (Source: CDC) The World Health Organization (WHO) states: “Over 1 billion young people (aged 12–35 years) are at risk of hearing loss due to recreational exposure to loud sounds.” (Source: WHO) From daily commutes and loud workplaces to concerts and headphone use, exposure to high sound levels adds up. NoiseShield gives you the tools to monitor and manage that risk in real time. Core Features Privacy-First Design NoiseShield does not record or save any audio. All sound level analysis is processed locally on your device, in real time. Real-Time Decibel Monitoring Continuously measures ambient sound levels using your device’s built-in microphone, with updates in real time. Smart Noise Alerts Receive automatic notifications when the noise around you exceeds safe thresholds, which you can customize (e.g., 70 dB, 85 dB, 100 dB). Background Monitoring Support NoiseShield can continue monitoring even when not in the foreground, depending on device capabilities and user permissions.
