Sound waves and acoustics
The numerous sound analysis and production tools make FizziQ an essential tool for studying sounds and acoustic physics in middle school, high school and university. discover FizziQ's many experimentation tools below: analysis tools, synthesizers and the sound library.
FizziQ's functionalities make it possible to study a wide variety of acoustic phenomena such as wave shapes (pure sounds, complex sounds and noises), interference effects (addition of sound waves, suppression of noises and acoustic beats), Doppler effect, measurement of the speed of sound, echolocation effects, acoustic resonance phenomena, definition of the range and timbre of musical instruments.
Study complex sounds with the tone generator
The sound synthesizer makes it possible to generate combinations of pure sounds on 3 independent channels. In combination with the tools of the microphone, the sound generator makes it possible to study the forms of pure and complex sounds, to work on the period and the frequency, as well as the scales or the sound beats.
Discover exciting experiences to conduct with the synthesizer and our sound activities aligned with the junior and high school curriculum.
Analyze the range or Doppler effect with the sound library
The sound library contains dozens of different sounds and noises that can be used directly in an investigation session. You will find in the library tuning fork sounds, musical instruments, white noises, and also sounds to work on the Doppler effect, echolocation, or the calculation of the speed of sound by determining knots. .
The oscilloscope
The FizziQ Oscilloscope, present in measuring instruments, allows you to analyze the shape of the sound wave detected by the microphone.
The oscilloscope is widely configurable:
10 and 100 ms scales
15Hz refresh rate
Sampling rates 4.8, 12, 24 and 48 kHz
Row or column display
Display of sound intensity in % of max amplitude
​Addition of the curve to the experiment notebook
The spectrometer
The FizziQ application spectrometer allows you to identify the frequencies present in the sound signal received by the microphone. The characteristics of the frequency meter are as follows:
Analysis of frequencies between 100 and 500 Hz
Resolution 20 hertz
15Hz refresh rate
Dominant frequency display with 1 Hz resolution
Row and column display
Addition to experience notebook
The frequency meter
The frequency meter in the FizziQ application allows you to measure the dominant frequency and the frequency present in the sound signal received by the microphone. The characteristics of the frequency meter are as follows:
Analysis of frequencies between 100 and 15000 Hz
Resolution 1 hertz
30Hz refresh rate
Historical and snapshot recording
Addition to experience notebook
The sound meter
The sound level meter measures the sound intensity detected by the microphone. The instantaneous measurement and the averaged measurement (noise measurement) are calculated. The characteristics of the sound level meter are as follows:
Sensitivity between 35 and 110 dB, variable depending on the smartphone
Resolution 1 dB
500Hz refresh rate
Row and column display
