BEAT FREQUENCY Meaning and
Definition
-
Beat frequency refers to the difference in frequency between two sound waves or oscillations that are superimposed on each other. When two waves with slightly different frequencies are combined, a new waveform is created where the amplitude varies over time. This variation in amplitude is perceived as a pulsating sensation called the beat frequency.
The beat frequency can be calculated by subtracting the frequency of one wave from the frequency of the other. For example, if two sound waves with frequencies of 440 Hz and 443 Hz are played simultaneously, the beat frequency will be 3 Hz (443 Hz - 440 Hz = 3 Hz). This means that the amplitude of the resulting sound wave will fluctuate at a rate of 3 times per second.
The beat frequency phenomenon is commonly experienced in music and acoustics. It is often utilized in tuning musical instruments, where a reference frequency is played alongside the instrument being tuned. The musician listens for beat frequencies to determine if the instrument is in tune or needs adjustment. The beat frequency is also used in sound therapy, where specific beat frequencies are believed to have beneficial effects on brainwave activity and relaxation.
In summary, beat frequency refers to the difference in frequency between two waves that are combined, resulting in a pulsating variation of amplitude. It is a fundamental concept in music, acoustics, and sound therapy.

Etymology of BEAT FREQUENCY
The word "beat" in the context of frequency originates from the 16th century Dutch word "bēten", meaning "to strike". It later derived from the Middle Low German word "bēten" and Old High German word "bōzan", both meaning "to beat". It found its way into English as an imported word in the 16th century.
The term "frequency" comes from the Latin word "frequens", meaning "frequent" or "crowded". It was first used in English in the early 17th century.
"Beat frequency" is a combination of these two terms. It refers to the difference in frequency between two sound waves, usually resulting in a periodic variation in volume or intensity. The term "beat" is used to describe the pulsation or rhythmic effect that occurs when two frequencies interfere and create a pattern of constructive and destructive interference.
