hi,
I'm not sure I completely understand the question but I'll give it a shot:
I read:
have no competences : I've got a buzzer which aims at producing a sound
what's a buzzer ? like a huge gameshow button ?
sequence when a certain default occurs. The buzzer behaviour is controlled by two parameters : its volume and the waveform used to produce the alarm sequence. It seems for many people that the alarm level is not enough strong, even at full blast so here's my question : do you know if there are some rules that make a sound appear more strong than another at an identic level ?
higher freuqncies are generally perceived as louder
Does the solution resides in considering a square wave (or whatever else) instead of a sine one ? Or should I have to set up a more complex waveform
square waves have rich harmonics = more high frequencies -> they will be per- ceived as louder than a pure sine at the same level.
(such as major chords, add a square to a sine...) ?
this might not work as expected, esp. since you'll require noticeable dynamic changes.
