What is the fundamental frequency also referred to in the context of harmonics?

The fundamental frequency is referred to as the first harmonic in the context of harmonics. This is because harmonics are multiples of the fundamental frequency, with the first harmonic representing the lowest frequency of a periodic waveform. When a sound is produced, it generates a fundamental frequency that determines the pitch perceived by the listener.

In a harmonic series, the first harmonic (or fundamental frequency) serves as the basis from which all other harmonics (higher frequencies) are derived. These higher harmonics are integer multiples of the fundamental frequency, such as the second harmonic (twice the frequency of the first) and the third harmonic (three times the frequency of the first). Understanding this concept is essential in speech science and acoustics, as it helps analyze the complex sounds produced in both speech and musical contexts.

Thus, knowing that the fundamental frequency is synonymous with the first harmonic allows one to appreciate the foundational role it plays in the overall sound spectrum and the relationships among various harmonics.
