What is the range of the beat frequency heard by the human ?

Explanation

To determine the range of beat frequency heard by humans, we can follow these steps:

### Step 1: Understand Beat Frequency
Beat frequency occurs when two sound waves of slightly different frequencies interfere with each other. The resulting sound has a frequency equal to the difference between the two original frequencies.

### Step 2: Identify Human Hearing Range
Humans can typically hear sounds in the frequency range of about 20 Hz to 20,000 Hz (20 kHz). However, the ability to perceive beats is limited to certain frequencies.
