    1) You must be patient. Sometimes it takes hours for a question to be answered.

    2) Your question is not simple. In English, the word Klaxon implies a very loud noise source, usually to announce emergencies. If that is what you want, you will probably not get a loud enough sound with either circuit. You will need some sort of amplifier. What kind of amplifier depends on what you need.

    Have you tried either circuit? You should experiment with different audio frequencies. The loudness of the sound will depend on the speaker, the speaker's enclosure, and the frequency used. There's no correct answer without extensive information (or experimentation).
