That used to be the sound that certain 2018+ Apple laptops with the T2 security chip made when performing an SMC Reset while the laptop was powered on. I have not heard that sound in a long while so I think a more recent macOS update has changed that behavior with the sound so I suggest making sure you have the latest macOS patches installed for your current OS.
I am also encountering issues powering on Apple USB-C laptops after an SMC Reset even with a fully updated macOS. Sometimes you need to unplug the charger for a few seconds and plug the charger back in. Then try powering on the laptop again. Sometimes you may have to wait a few minutes and the laptop will automatically power on by itself. If that does not work, try connecting the charger to another USB-C port especially on the other side of the laptop if you have the four port model.
I have not been able to determine any hardware issues with the laptops exhibiting this behavior. I believe this is just Apple doing a terrible job with hardware design and implementation and poor system firmware. This is just one of many disturbing behaviors I've encountered with these Apple USB-C laptops and it makes troubleshooting these laptops an extremely difficult process.
