The frequency range for normal speech is typically between 125 Hz and 8,000 Hz. Most speech sounds fall within this range, with vowels generally lower in frequency and consonants higher in frequency.
Whispering typically falls within the frequency range of 1,000-4,000 Hertz. The sound produced during whispering tends to be softer and higher in frequency compared to normal speech.
frequency
Normal breath frequency for adults at rest is typically 12-20 breaths per minute. However, this can vary depending on factors such as age, fitness level, and underlying health conditions. It is best to consult a healthcare provider if you have concerns about your breathing frequency.
The frequency of the lowest sound that the normal human ear can perceive is generally considered to be around 20 Hz. Below this frequency, the sound is typically felt as vibrations rather than heard.

frequency
No. Frequency is just a measure of "how often". It can be less than, equal to or greater than normal.
Most people with 'normal' hearing can perceive sound up to 18,000 Hertz. The higher frequencies become less audible with age.
the wavelength changes when the frequency changes if the wavelengths are smaller and thinner then the frequency is high, when the frequency is slow then the wavelengths is larger and wider. if the frequency is constant then the wavelength is a normal size
Because a dolphin's ear frequency is higher than a normal human's, so they have to have higher pitched whistles so the dolphins can here them better. Plus, high sound frequencies can travel underwater easier so dolphins can hear them.
Normal frequency range for amplitude modulation is 550kHz to 1610kHz
