What happens to noise when frequency of the wave decreases?
When the frequency of the wave decreases, the pitch of the noise decreases, making it sound lower. The noise may also become more rhythmic or repetitive as the frequency decreases. Additionally, lower frequency noises can travel further distances and penetrate obstacles more effectively.
How would you eliminate the high frequency noise in integrator?
To eliminate high frequency noise in an integrator, you can use a low-pass filter at the input of the integrator to block high frequency signals. You can also increase the integration time constant to filter out high frequency noise. Additionally, using a precision op-amp with good common-mode rejection can help reduce noise in the integrator circuit.
Is low frequency dangerous and how does it impact our health and well-being?
Low frequency itself is not inherently dangerous to human health. However, prolonged exposure to low frequency noise, such as from industrial machinery or traffic, can have negative effects on our health and well-being. This can lead to issues such as sleep disturbances, stress, and even potential long-term health problems like cardiovascular issues. It is important to limit exposure to low frequency noise to protect our overall health.
What sound is in the 6K hz range?
A sound in the 6 kHz range would be in the higher frequency range of human hearing. It is typically described as a high-pitched tone similar to a squeal or whine. This frequency range is commonly used in audio equipment testing and calibration.
What are the effects of lower amplitude on the frequency response of a signal?
Lower amplitude of a signal can result in a decrease in the signal-to-noise ratio, making it harder to distinguish the signal from background noise. This can lead to a loss of clarity and accuracy in the frequency response of the signal.
Which type of noise has sound at every frequency within the range of human hearing?
White noise
Which frequency range of human hearing is most affected by hazardous noise?
3,000-6,000 Hz +++ Noise at hazardous levels are so over the entire human audiological spectrum, but long-term exposure reduces the response from the highest frequency (18-20 kHz) downwards.
What types of noise are frequency independent?
noise are assumed frequency independent......
Why is amplitude modulation susceptible to noise but not frequency modulation?
because noise usually changes the amplitude not frequency.
Which noise becomes a great importance at high frequency?
SHOT Noise
When an audio cable connected to a stereo makes noise because it touched a human- is that because humans have a natural frequency inside them or something along similar to that?
No. The noise you hear is from imperfections in the circuitry, causing a hum.
What happens to noise when frequency of the wave decreases?
When the frequency of the wave decreases, the pitch of the noise decreases, making it sound lower. The noise may also become more rhythmic or repetitive as the frequency decreases. Additionally, lower frequency noises can travel further distances and penetrate obstacles more effectively.
If sampling frequency doubles then quantization noise?
reduces

Why can't humans hear the sound of a bat?
Bats use echolocation to sense movement and their surroundings. We cannot hear the high pitched noise they emit because it is of a higher frequency than the human ear can register. There are some sounds of a bat that we can hear, but the sounds that we can't hear is because the squeaks are so high that you really need ultrasound to hear it.
Which headphones rated the highest for noise cancelation?
The headphones that are rated the highest for noise cancellation are Bose headphones. They are recommended for long flights and for times when you will want to cancel out outside noise.
