Really depends on the exact drive model sometimes. For example, Seagate's IronWolf has two variants of 10/12 TB drives, with one of them having a seek noise level of 26-28 db, and another one ranging on 32-34 db. WD Red Plus also has a 10 TB drive with noise levels of 38 db during seek, while a 14 TB one reaches just 29 db during seek... There is a 10 TB Red Pro revision with just 20 db of idle noise, while another revision reaches 34 db, which is just insane.

Admittedly, I'm too lazy to look up Toshiba drives, since there seems to be way too many lineups...
Down below, the same table, just with the drives ordered according to their seek noise level.

There is also conflicting information regarding some Seagate drives. Some drives' datasheets inform noise levels of 18/20 db idle, but the user manual (which is what I used here) indicates 28/30. In those cases, I went with the worst case scenario.
