This option will turn on the "visible bell", i. e. a visible notification shown every time that normally just a bell would occur. This is especially useful for deaf people.
Dizze opsje skeakelet de "sichtbere bel" yn, oftewol in sichtbere meidieling dy' t te sjen is op it momint dat it lûd de bel te hearren wêze soe. Dit is benammen brûkber foar dôven en minsken dy' t net sa goed mear hearre kinne.
