Pulse Echo Sonar Meter

Pulse Echo Sonar Meter is designed to harness audio output to create sound pulses, capturing echoes through the microphone for exploration of acoustic principles. This Android app offers a dynamic tool for investigating audio signal behaviors and characteristics, allowing you to visualize echo data in various formats such as maps, Fourier transforms, and time-series waveforms. Ideal for educational and research purposes, Pulse Echo Sonar Meter facilitates a robust learning experience in acoustics, making complex concepts accessible through hands-on experimentation.

Comprehensive Acoustic Analysis

By using Pulse Echo Sonar Meter, you can engage in detailed acoustic analysis with features like echo visualization and frequency content assessment. The app supports a sampling frequency of 44.1 kHz, with durations ranging from 0.001 s to 5 s, giving you flexibility in data collection. Generate pulses in single or continuous modes with options for chirp or train patterns and select square or sine waveforms. Such versatility allows for a tailored investigation of sound behaviors across a frequency range of 20 Hz to 22.05 kHz.

Visual and Data Export Options

Pulse Echo Sonar Meter enhances your research capabilities by offering visual echo mapping in color or black and white, reflecting RMS or absolute values. By moving your device during pulse-echoing, you can create detailed maps for more comprehensive insights. Additionally, the ability to perform Fast Fourier Transform (FFT) of 8192 data points and save data in CSV files is particularly beneficial for those needing to document and analyze experimental results. Peak frequency detection and FFT averaging further solidify the app’s utility for serious acoustic examinations.

Enhanced Safety and User Experience

While leveraging Pulse Echo Sonar Meter's advanced functionalities, it's essential to note its limitations with typical microphone ranges, making distant echo detection challenging without extra amplification. Users are advised to consider ear protection during pulse generation due to potentially loud sounds. While this app is not intended for medical imaging, its educational value is significant, providing a rich, interactive platform to explore acoustical concepts.
