What are the frequency bounderies for Far Field analysis?
Far Field analysis has a lower and upper frequency bound. The lower bound indicates from which frequency the sound image can show results. The upper bound indicates from which frequency spatial aliasing can happen.
Microphone array
This blog is useful for users who are interested in technical details of sound imaging.
With the insights we share, you will have a better understanding of the physical layout and size of a microphone-array.
This will particularly help you in selection of hardware and understanding the results of a recording.
Detection of sound leakages
This blog is useful for developers and installers of separation walls, seals, doors, windows and more.
With the insights we share, you will have a better understanding of detection acoustic leaks.
This will particularly help you in the working method to get fast and accurate results.
Spectral Analysis, your spectrum of frequencies
This blog is useful for acoustic engineers and managers.
With the insights we share, you will have a better understanding of a frequency spectrum and detection of peak-frequencies in the environment.
This will particularly help you in performing effective beam-forming or far-field analysis.
It also helps explaining frequency-related issues to less experienced people.
Spectrogram analysis waterfall diagram
The Spectrogram is a time-frequency diagram.
The X-axis of the spectrogram displays the time from left to right. The Y-axis of the shows frequencies.
The colours in the spectrogram represent the intensities of a frequency at a certain time. An intense colour means a strong pressure of that frequency was recorded at that point in time.
