  Pure tone - Wikipedia, the free encyclopedia
A pure tone is a single frequency tone with no harmonic content (no overtones).
It is characterized by the frequency — the number of cycles per second, the wavelength — the distance the waveform travels through its medium within a period, and the amplitude — the size of the cycles.
The lowest of these frequencies (the fundamental frequency) determines the pitch of the tone, which is perceived by the human hearing.

 Aarktica :: Pure Tone Audiometry reviews
Pure Tone Audiometry refers to the series of tests to determine hearing sensitivity which Jon DeRosa, aka Aarktica, went through after permanently losing the ability to hear on his right side.
Pure Tone Audiometry is the third album by DeRosa as Aarktica (he also plays in a country band called Pale Horse And Rider), and it takes nearly equal parts from both of his first two releases, blending drone with slight touches of electronic rock into another excellent album.
Pure Tone Audiometry is a trip into a sonic plane that soothes while revealing feelings of loneliness and emptiness.

 Pitch paradoxical
A harmonic tone consists of a sum of pure tones (each one called a partial), whose frequencies are in integer ratios of 1, 2, 3,...
The pitch of a harmonic tone is defined to be its fundamental frequency, which is the frequency of the pure tone which has the same pitch.
In fact, the second G2 tone in the first sequence and the second G3 tone in the second sequence are the same harmonic G2 with its fundamental missing.

 Pure Tone Files - Subwoofer Test Pattern
The pure tone files (which are included in both the Basic and Premium tests) are composed of 26 sine signals, a total of 52 files: one set of sine signals of equal phase for the right and left channels and one set of sine signals which have waves out-of-phase for the right and left channels.
If you don't hear the lowest tones, try the higher frequencies — the problem could be your hardware, not your audio system's.
When your speakers are properly connected, the out-of-phase tones should produce a lower volume version of the sound compared to the in-phase audio file.

We'll examine that subject in the next section but first it is instructive to listen to the two pure tones and to the complex tone that results from their addition.
First note that the pure tones sound a little mechanical whereas the complex tone sounds a bit more like what we would associate with a note from a musical instrument.

 PURE TONE   (Site not responding. Last check: 2007-11-07)
A pure tone is described by a sine wave, a mathematical function based on the circle.
The sine wave for each tone has a specific frequency (hertz [Hz], or cycles [repetitions] per second), amplitude or power (size, strength) in decibels (dB), and phase (time relation to other the sound waves).
This means that the second line has exactly the same number of cycles (or peaks) per second, but its size is half the size of the top line, and its peak pressure comes slightly later than the peaks of the top line.

 Audiometry: the Testing of Human Hearing
The testing of hearing is most often carried out by establishing the threshold of hearing, the softest sound which can be perceived in a controlled environment.
It is typical to do this testing with pure tones by providing calibrated tones to a person via earphones, allowing that person to increase the level until it can just be heard.
Various strategies are used, but pure tone audiometry with tones starting at about 125 Hz and increasing by octaves, half-octaves, or third-octaves to about 8000 Hz is typical.
