Sound Level Analyzer Lite - Simple dB Meter
Achieved over 100,000 app downloads, "Sound Level Analyzer / Lite", #1 Sound Level Meter app for iPhone !
"Sound Level Analyzer Lite" is a Sound Level Meter app for iPhone. This app is a free edition that is simplified the powerful sound analyzing tool, "Sound Level Analyzer".
Available in variety of applications as the neighboring environmental noise measurement, audio system check, vehicle interior noise check, sound check of live events, and more.
With a built-in iPhone's microphone, this app could display neighboring mean sound level and the minimum, the maximum value just to set ANSI filter characteristic (A/C/Z) and time characteristic (FAST/SLOW). It also has the calibration function to adjust the microphone level for each device.
By the Ver 2.0, the measurement display of the long-term average equivalent sound level has been added as a new feature. You can know the time-averaged noise level easily.
*** Newest Release App ***
Now released new powerful noise generation tools, "Octave Band Noise Generator / Lite - free of charge“, as the best sound source for environmental sound measurement, sound tuning, auditory effects like tinnitus relief and sound masking. It can generate the programable noise signal by using the band-pass filtering of 1/1 and 1/3 octave band with ideal steep attenuation characteristics.
Features :
- Sound Level Measurement function:
"Leq" (equivalent continuous sound level),
"Lmin" (Minimum sound level of Leq),
"Lmax" (Maximum sound level of Leq),
"Leq ave" (Long-term average equivalent sound level).
- Display range : 0 - 130dB (measurement range: 20 - 110dB)
- Frequency weighting : A and C weighting filters, Z (None weighting)
- Time weighting : Fast=125ms / Slow=1.0sec
- Calibration function : -20 - +20dB / 1dB unit
- Measurement time : 20 sec
Example of Noise level :
- 130dB : airplane engine sound
- 110dB : horn of the car
- 100dB : train passing sounds
- 90dB : noisy factory
- 80dB : on the train, vacuum cleaner
- 70dB : noisy office, street
- 60dB : quiet car, normal conversation
- 50dB : quiet office
- 40dB : library, quiet residential area
- 30dB : midnight suburbs, whisper
- 20dB : sound of rubbing leaves
Note:
The WHO has proven direct links between noise and health risks; tinnitus, sleep disturbance, stress, cognitive impairment, heart diseases and annoyance in general. Please check your environmental noise for your wellness.
This app is adjusted the reference value for iPhone. However, the built-in microphone of your iPhone is likely to have a non-uniform gain. The more exact measurement should be calibrated using the absolute level calibration devices.
The authorization for access to the built-in microphone will be confirmed by the iOS system at first boot. Please enable access to the microphone.
For a more detailed sound analysis, we recommend that you choose our high performance app "Sound Level Analyzer" which has a powerful sound level measurement & precise sound analysis functions.
For the analysis of low-frequency vibration, please try the vibration measurement app "Vibroscope". In Addition, Noise Viewer” can visualize the frequency fluctuation in the noisy sound. It can detect the frequency variation noise that can not be measured by the traditional sound analysis. It will help you discover the noise detection and its causes.
TOON,LLC is a company that seeks the comfort of sound environment based on our acoustic proprietary technology, and we will provide tools for audio professional, sound technology, home theater installer, and anyone who loves audio.
