Update on coil whine - a significant discovery may have helped me find a solution.
TLDR: My coil whine was awful. However, it was connected to an extension lead as my TV is too far from a wall socket. Connecting the Pro to the wall socket directly almost dramatically improved the noise issue.
More detail:
I came across this by accident. I asked ChatGPT whether this could actually be possible, or whether I was just imagining it. As some of you might know from your research already into the causes of this, the coil whine is caused by electromagnetic interference. Initially, we focused solely on the make-up of the circuitry (the PSU and motherboard in general), but if you factor in the transmission of voltage outside, too, you might find another factor:
This time, I needed evidence, so I ran a little experiment.
I recorded the sound plugging in directly into the wall socket. We'll call this Example A. Here is the chart.
I uploaded these to the AI bot, and I kid you not, this is the exact analysis it gave me.
- The peak at 73 Hz is likely a low-frequency hum or vibration (possibly a mechanical issue, such as coil whine or fan imbalance in electronic devices).
- The peak at 354 Hz indicates a higher-frequency sound that might also be related to mechanical vibrations or electrical interference.
This is Image B (extension lead).
In
Image B, the noise is concentrated at a higher frequency (649 Hz). In terms of the coil whine, it is 83% higher using the extension lead. This is why perhaps there is a variance in reports of noise: the PS5's design may be inherent to these, but depending on the quality/state of your extension lead/wall socket, it could worsen or subdue the level of EMI, and thus the sound you hear as a result.
