Bluetooth Speaker Mic vs Decibel Meter Sonolab

Turn your iPhone into a live microphone and hear your voice come out of the speaker you are already connected to. Bluetooth Speaker Mic amplifies what you say in real time through a Bluetooth speaker, AirPlay device, wired output, or the phone's own speaker. No extra hardware to buy — just connect, press start, and speak. WHAT IT DOES Speaker Mic uses your iPhone microphone as a live input and sends your amplified voice straight to the current audio output. Give a toast, run a small class, call the kids in from the garden, lead a workout, or simply add presence to your voice at a gathering — all with the speaker you already own. There is nothing new to charge and nothing extra to carry: if your phone can reach the speaker, it can become your mic. Because it works over standard Bluetooth audio, expect a short delay of roughly 150–250 ms between speaking and hearing yourself. This is normal for wireless audio, not a fault. For the cleanest sound, keep the phone away from the speaker so the mic does not pick up the output and create feedback (that whistling squeal). A wired connection or AirPlay usually feels tighter than Bluetooth. GREAT FOR • Toasts, speeches, and announcements at parties • Teachers, coaches, and tour guides who need a little more volume • Home karaoke and sing-alongs through your speaker • Reaching someone in another room or across the yard • Small presentations and meetings without a PA system FEATURES • Live input level (VU) meter so you can see your voice register in real time • Clear output-route indicator — always know if sound is going to Bluetooth, AirPlay, wired, or the phone speaker • Adjustable gain to set exactly how loud your voice comes through • Reverb to add a touch of room, hall, or stage character • EQ presets to warm up or brighten your voice • Optional local recording saved as M4A, kept privately on your device • Clean, simple interface built for one-hand use • Works with the Bluetooth or AirPlay speaker you already have FREE VS PRO Free: the live microphone, real-time amplification to any connected output, the VU meter, the output-route indicator, gain, and up to three saved recordings. Pro: unlock every reverb and EQ preset, extra accent themes, and unlimited local recordings — everything, with no limits. HOW IT WORKS 1. Connect your iPhone to a Bluetooth or AirPlay speaker (or plug in, or use the phone speaker). 2. Open Speaker Mic and press Start. 3. Speak — your voice is amplified live through that speaker. Move the phone away from the speaker to avoid feedback. HONEST NOTES This app amplifies and lightly shapes your live voice; it is not a studio recording rig and does not remove the small wireless delay that Bluetooth introduces. Final volume depends on your speaker, so a louder speaker means a louder you. Everything runs on your iPhone — there is no account to create, no cloud upload, and no tracking. Your recordings stay on your device, and you can delete them anytime. SUBSCRIPTION Speaker Mic Pro is a subscription. Weekly is $3.99 after a 3-day free trial; yearly is $17.99.

SonoLab turns your iPhone into a powerful decibel meter and noise dosimeter, helping you understand how loud your environment really is. See sound levels live, track noise exposure throughout your day, and explore frequencies in real time — all using your iPhone’s built-in microphone. Whether you’re checking noise on a plant floor, tuning a studio, working in a busy classroom or hospital, making music, or simply keeping track of a noisy environment, SonoLab gives you the tools to measure, understand, and document sound. THE DECIBEL METER Choose from nine measurement views, from detailed statistics to beautifully visual ways of experiencing sound: • Bench — See a complete set of measurements including LAeq, LAFmin, L90, L10, LAFmax, and LCpeak • Survey — Walk around your space and add markers directly to the measurement trace • Limits — Quickly compare LAeq, LCpeak, and dose with your selected limits • Steady — Know when a measurement has settled and you’re ready to stop • Orbit, Trails, Nova, Ripples, and Eclipse — Experience the same sound measurement through dynamic visualizations Choose A-, C-, or Z-weighting, with Fast (125 ms) or Slow (1 s) response. You can also calibrate SonoLab using a 94 dB reference or another trusted meter, with your calibration offset applied throughout the app. THE NOISE DOSIMETER Track your noise exposure throughout an entire work shift. The dosimeter works like a shift clock, showing how your exposure builds over time. • See Dose %, 8-hour TWA, and the estimated safe time remaining at your current sound level • Choose OSHA, NIOSH, or NOM-011 criteria and see all calculations update automatically • Mark breaks so quiet periods aren’t counted as part of your exposure • Keep measuring in the background while you work FREQUENCY ANALYSIS Take a closer look at what makes up the sound around you with six real-time analyzer views powered by FFT analysis: • Octave-band bars and a 60-second waterfall spectrogram • Peak hold and a visual representation of the last two minutes of sound • RTA Pro — detailed 31-band third-octave analysis with an NC room rating and the band responsible for the rating • Keys — see your sound mapped across a piano keyboard and identify the loudest note HISTORY AND REPORTS Your measurements are automatically organized into sessions, including sound levels, statistics, and noise exposure. Rename sessions, review measurement traces, save spectrum snapshots, and export professional PDF reports with your measurement settings included. Your history is backed up with iCloud, so your measurements can stay with you when you move to a new iPhone. ALERTS Want to know when noise gets too loud? Set your own threshold and SonoLab can vibrate, flash the screen, or send a notification when the sound level crosses it — even while measuring in the background. A NOTE ON ACCURACY SonoLab is designed for surveys, awareness, monitoring, and documentation. An iPhone microphone provides an estimate rather than a certified measurement and may vary by a few dB or clip at very high levels, typically around 100 dB. For the most reliable results, calibrate SonoLab against a trusted reference. When measurements need to meet formal compliance requirements, use a certified Class 2 sound level meter. SonoLab is a powerful tool for understanding and documenting sound, but it is not a replacement for certified professional equipment. PRIVACY Audio is analyzed in real time. SonoLab never records or stores your audio.
