Higher headquarters assessments are typically conducted annually or semi-annually, depending on the specific policies and procedures of the organization. However, some assessments may be conducted more frequently, especially if there are significant changes to operations or security posture.

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.

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.
Infrasound refers to sound waves with frequencies below the range of human hearing (below 20 Hz), while ultrasound refers to sound waves with frequencies above the range of human hearing (above 20 kHz). Infrasound is used in monitoring seismic activity and animal communication, while ultrasound is used in medical imaging, industrial cleaning, and pest control.
An example of allele frequency is when in a population of 100 individuals, 60 individuals have the dominant allele (A) for a specific gene, while 40 individuals have the recessive allele (a). The frequency of the dominant allele (A) would be 0.6, and the frequency of the recessive allele (a) would be 0.4.
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.
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
