If you have never heard before, here is how gravitational waves of merging two massive (>20 Solar masses) black holes sound like:
Here is the audio of merging neutron stars (sound is audible in the last few seconds):
I made a small web app to train yourself to ‘whistle’ a gravitational wave (if on mobile, use landscape mode): https://kaurov.org/gw
It may ask you to allow the browser to use the microphone. Obviously you should agree. There is no reason not to trust me… Really*…
Current version of the script shows only the total mass of the final object. The calculation is performed through the calculation of the chirp mass from the frequency and its derivative assuming that the component masses of the initial two-body system are equal.
It is actually quite hard to mimic any of the measured signals (with high masses).
I am happy to hear any suggestions and to collaborate on equally useful projects.
