A perforated ear drum could occur if
- you were exposed to intermittent noise above 25 kHz.
- you frequently blew your nose with excessive force.
- you were subjected to continuous noise below 8 kHz.
Explanation from PART66Online
The eardrum can be perforated by a sudden pressure surge transmitted up the Eustachian tube, such as blowing the nose too forcefully. Ordinary continuous or intermittent noise at the levels stated does not rupture the membrane; it is the abrupt mechanical overpressure that tears it.

it is normal but the answer says "continuous" which is bad regardless the frequency.
