What is decibels (dB)?What is decibels (dB)?
Effortless hearing, stylish, discrete & packed full of features. We love this hearing aid. The volume or intensity of sound is measured in units called decibels (dB), generally on a scale from zero to 140 (any higher than 140 and you are in trouble immediately).
What is the signal strength at-65 decibels?What is the signal strength at-65 decibels?
Hypothetically speaking, if your device's radio receives a signal at -65 dBm (decibels per milliwatt), and the noise floor is -80 dBm, then the resulting signal to noise ratio is 15 dB. This would then reflect as a signal strength of 15 dB for this wireless connection.
What does an SNR of 95 dB mean?What does an SNR of 95 dB mean?
For example, an SNR of 95 dB, means that the level of the audio signal is 95 dB higher than the level of the noise. Which, in turn, means that an SNR of 95 dB is better than one that is 80 dB. How to Calculate Signal to Noise Ratio SNR calculations can be either simple or complex, and it depends on the devices in question and your available data.
