Higher in frequency.
frequency
The sound pressure amplitude tells about how loud the tone will be and the frequency (cycles per second) of the oscillation tells how high the sound of the tone will be. The amplitude gives the loudness of the tone: http://en.wikipedia.org/wiki/Loudness The frequency gives the pitch of the tone: http://en.wikipedia.org/wiki/Pitch_%28music%29
Loudness, pitch and timbre are approximately the correlates of signal amplitude, frequency and frequency spectrum, respectively.
Tone
A tone is a frequency and sound is a frequency therefore a sound is a tone.
Sounds consist of fundemental tones and overtones. A single frequency is a fundemental tone.
Higher in frequency.
It is concerned with frequency.
The note, the frequency or the wavelength.
frequency
The sound pressure amplitude tells about how loud the tone will be and the pitch (frequency = cycles per second) of the oscillation tells how high the sound of the tone will be. The amplidude gives the loudness of the tone. The the pitch gives the frequency of the tone.
Frequency
If you subtract from the carrier frequency the frequency of the tone that modulates it, then filter out the carrier frequency, then you have a lower sideband frequency. If you add to the carrier frequency, filter out the carrier, then you have an upper sideband frequency.
The Taurus' and larger Fords have a traditional "two-tone" horn - a higher frequency tone combined with a harmonic lower frequency tone. I believe the smaller vehicles have only a single tone horn (might be why they sound rather wimpy)
