How is the WD RED PLUS 12 TB quieter than the 6 TB versions?

Hello,
I do not understand. The 12 TB and 14 TB are 7200 rpm, the 6 TB is 5400 rpm. Doesn't the noise level depend on the rpm?

According to the WD documentation:

12 TB (WD120EFBX) or 14 TB

Iddle: 20 dB SeeK: 29 dB

6 TB (WD60EFZX)

Iddle: 25 dB SeeK: 30 dB

So far, I didn't want to buy a 2 bay, 2 x 12 TB HDD because I thought it would be noisier than a 4 bay, 4 x 6 TB HDD.

What is the truth?

I'm surprised you can hear the drive to begin with
- You need to be deaf to not hear an HDD, and Helium one are generally very noisy.
