A nice question. Well, we can reduce the noise or we can increase the signal. We assume you are using components that are inherently low noise in themselves.
Consider a passive antenna. A simple dipole will have a broad directional receiving pattern, but your signal is coming from only one direction. So by converting to a directional antenna, such as a Yagi antenna, or a parabolic dish, you can narrow the receiving direction(s) to cover only a few degrees, rather than over 100 degrees. Thus a Yagi antenna may be described as having a gain of 20dB. That is not real gain in signal strength, just a gain in signal-to-noise ratio.
Similarly tricks are available with electronics. The ingenious Mr Dolby has given us a method whereby we divide our signal band into several segments. If at a given moment there is no signal in one segment, then that is not amplified, whereas the segments in which there is signal, are amplified. Only practicable with high speed electronics, but they are available - so go for it.
And again with broadband noise degrading our signal. If the same noise signal is present at bands adjacent to that of our interest, then if we cancel that moment of signal on all bands, we may improve our signal to noise ratio. This trick is used in cleaning up 'pops' from scratches on vinyl records. The momentary loss of signal is less troublesome than the presence of a pop. High speed electronics to the rescue again!
As so strengthening the signal itself, simple amplification or reduced bandwidth are approaches that produce results.

What do engineers use the signal to noise ratio for?
Signal to noise ratio is a measure of signal strength to the background noise. Engineers use the signal to noise ratio to improve digital signal processing.

A preamp A preamp.
How do you calculate Signal to Noise ratio?
It can be calculated by simplifying the ratio between power of signal by power of noise
What is the difference between Signal-to-Noise Ratio (SNR) and Noise Reduction Rating (NRR) in the context of audio equipment?
Signal-to-Noise Ratio (SNR) measures the quality of the signal compared to the level of background noise, indicating how clear the audio is. Noise Reduction Rating (NRR) quantifies how much external noise is reduced by a device, such as headphones or earplugs, to improve the listening experience.
What is the signal to noise ratio for the Kenwood KDC-C471FM?
The Kenwood KDC-C471FM has a Signal-to-noise ratio of 100 dB
What is the signal to noise ratio formula in dB?
The signal-to-noise ratio (SNR) formula in decibels (dB) is calculated as 10 times the logarithm base 10 of the ratio of the signal power to the noise power. The formula is: SNR(dB) 10 log10(signal power / noise power).
In an amp What is better high or low signal to noise ratio?
Signal to noise ratio is the difference between the noise floor and the reference level.
What is the difference between the noise reduction ratio (NRR) and the signal-to-noise ratio (SNR) in audio processing?
The noise reduction ratio (NRR) measures how much background noise is reduced by a device or process, while the signal-to-noise ratio (SNR) compares the level of the desired signal to the level of background noise present in audio processing.
Signal to noise ratio?
Noise signal is any signal which interferes with the main signal and does not give any important information.Signal should always be twice to that of noise.
What is Sinr?
Is that the signal interference + noise ratio?
What is Sound to noise ratio?
The signal-to-noise ratio (SNR) is a measurement used in audio engineering and telecommunications to refer to the ratio of the power of a signal (like sound) to the power of background noise. A high SNR indicates a high-quality signal with less interference from noise, while a low SNR indicates a weaker signal that may be harder to distinguish from background noise.
