-
Definition and Calculation
SNR is expressed in decibels (dB) and represents the ratio of the power of the desired signal to the power of the unwanted noise. It is calculated as 20 log10 (Signal Amplitude / Noise Amplitude). A value of 60 dB implies that the signal is 1000 times stronger than the noise. The higher the dB value, the better the microphone’s performance in capturing the intended sound while minimizing interference. For example, a microphone with an SNR of 80dB would be preferable to one with 60dB, assuming all other factors are equal.
-
Impact on Recording Quality
A low SNR can result in recordings dominated by hiss, hum, or other undesirable sounds, making it difficult to isolate the intended audio. This is particularly problematic in mobile recording scenarios, where environmental noise is often unavoidable. Low light scenarios or recording with high gain can also impact this specification. Conversely, a high SNR allows for clearer and more detailed recordings, even in challenging acoustic environments. Clear voice can be more important than the video. Consider a scenario in a crowded urban environment where a high-SNR microphone effectively captures the speaker’s voice while suppressing traffic sounds.
-
Relationship to Microphone Sensitivity
Microphone sensitivity relates to how well a microphone converts sound pressure into an electrical signal. A very sensitive microphone might also amplify background noise if its internal circuitry isn’t optimized to minimize self-noise. SNR is often a better indicator of overall performance than sensitivity alone because it directly addresses the balance between signal strength and noise floor. In practice, a microphone with moderately high sensitivity and a high SNR generally outperforms one with extremely high sensitivity and a low SNR.
-
