What else can I help you with?
Why there is a clipping in the signal output when you change the attenuation from 20db to 0 db in function generator?
A: Clipping only occurs if the input surpasses a threshold like the Vbe of a transistor. The 20 Db is really a change3 in voltage of a 100 that is not a small change
If transmitter power is increased from 200 Watts to 400 Watts how do you convert to Db form?
Decibels (db) is relative power, log base 2, times 3. Increasing power from 200 watts to 400 watts is doubling power, so the decibel change is +3 db.800 watts would be +6 db, 1600 watts would be +9 db, 100 watts would be -3 db, 50 watts would be -6 db, and so on.
Prove dbm plus dbm equals db?
The decibel scale is a logarithmic scale where each change in three dB represents a power factor change of two. (3 dB is power times two, 6 dB is power times four, 9 dB is power times 8, etc. Similarly, -3dB is power divided by two, -6 dB is power divided by four, etc.) Zero dB is assigned some arbitrary reference power. One example is 1 mV across 600 ohms. If you double the voltage into a constant resistance, the power quadruples, so 2 mV would be +6 dB, 4 mV would be +12 dB, etc. The letter after dB is the reference power. In the case of dBm, it means that 0 dB is 1 milliwatt, so 2 milliwatt is +3 dB, etc. There are many dB scales, such as dBa, used in sound measurements. Still, fundamentally, 3 dB is a doubling of power, -3 dB is a halving of power, so, for any arbitrary scale, say dBq, then saying +6dBq is saying a power four times higher than 0 dBq. In the end, dBm plus dBm is delta dB, with no scale.
How loud is 60 db?
60 dB sound pressure level is about conversational speech listened in 1 meter distance.
What connector is used in RS-232 transmissions?
DB-25 D-Sub-9 or D-Sub-25
Threshold of human in db?
The threshold of hearing is 0 dB. The threshold of pain = 137.5 dB.
How much dB you can hear by your ears?
You can start to hear at the threshold of hearing at 0 dB and end up at the threshold of pain at 137.5 dB.
How many decibels are in your pain threshold?
That depends on the listening person. 120 dB will bring you pain.
What decibel range can a human hear in?
We can hear from 0 dB, that is the threshold of hearing up to 130 dB that is the threshold of pain.
What SPL is the threshold of pain?
130 dB is an SPL commonly considered to be the threshold of pain. Between 120 and 140. http://ccrma-www.stanford.edu/~jos/st/DB_SPL.html
Does loudness hurt?
It depends on how loud it is. In hearing, the threshold of pain is the sound pressure or sound pressure level beyond which sound becomes unbearable for a human listener. This threshold varies only slightly with frequency. Different values for the threshold of pain are found in the literature: Here are some sound pressure levels SPL in dB and the sound pressure in pascals of the sensed possible threshold of pain: SPL 120 dB = 20 Pa SPL 130 dB = 63 Pa SPL 134 dB =100 Pa SPL 137.5 dB =150 Pa SPL 140 dB =200 Pa
What is the maximum and minimum intensity of sound that human call can ear?
The human ear can typically detect sound intensities ranging from about 0 dB (threshold of hearing) to 120-130 dB (threshold of pain). Sounds below the threshold of hearing are too faint for the ear to detect, while sounds above the threshold of pain can be physically uncomfortable or damaging to the hearing.
What is the number of decibels a human being can hear?
The average human can hear sounds ranging from 0 dB (threshold of hearing) to around 120 dB (threshold of pain). However, the range of comfortable hearing is typically between 20-70 dB for most people.
What is the average sound level?
The usual soundlevel can be between 0 dB SPL = 20 µPa (threshold of hearing) up to 130 dB SPL (threshold of pain). An average sound level could be at 85 dB SPL. Scroll down to related links and look at "Average sound pressure levels".
What is the range of the threshold of human hearing and the threshold of pain?
It varies from person to person. However - an accepted 'normal' hearing range is around 20 Hz to 20,000 Hz. The same goes for pain threshold - anything over 120 dB would certainly be uncomfortable for most people.
How loud or soft a sound is perceived to be?
The perception of how loud or soft a sound is depends on the intensity of the sound wave, measured in decibels (dB). The range of human hearing typically spans from 0 dB (threshold of hearing) to 120 dB (threshold of discomfort or pain). The perceived loudness also varies based on individual hearing sensitivity and the frequency of the sound wave.
How many decible can aman hear?
The average human ear can typically hear sounds in the range of 0 decibels (dB), which is the threshold of hearing, up to about 120-130 dB, which is the threshold of pain. Sounds above this range can cause discomfort or hearing damage. Individual sensitivity may vary, and prolonged exposure to sounds above 85 dB can lead to hearing loss.
