Acoustic Applications of Audio Test Tones
Pure Sine Waves vs Periodic Harmonics
A pure sine wave contains strictly a single fundamental frequency with zero harmonic distortion (THD ≈ 0). It is ideal for calibrating speaker enclosures, pinpointing room standing modes, and testing subwoofer port resonance calibrated to ISO 16 standard concert pitch (A4=440Hz).
Logarithmic Frequency Sweeps & Impulse Response
A logarithmic frequency sweep (chirp) excites the full audible spectrum continuously from 20 Hz to 20,000 Hz, making it indispensable for measuring room acoustic transfer functions, reverberation time (RT60), and loudspeaker distortion profiles.
