What is Signal to Noise Ratio? Why does it matter?

At Audioengine, we're committed to engineering home audio systems that go beyond ordinary sound reproduction. One key element that sets us apart is called “Signal-to-Noise Ratio (SNR)”. 

In this article, we'll explain what SNR is and why it's crucial for anyone serious about their music. 


What is a Signal to Noise Ratio and why does it matter? 

Signal-to-Noise Ratio, or SNR, is essentially a measure of clarity. It tells us how much clearer the music is compared to any background noise in the system. The higher the SNR, the less interference you'll have from background noises like hums, hisses, or pops. Imagine trying to hear a whisper in a tranquil library versus a bustling café. 

Engineering for Reduced Noise 

Our home music systems are designed to minimize the distractions that can dilute your listening experience. Here's how: 

  • Balanced Circuits: These eliminate noise from household electrical sources, like your fridge or TV, ensuring that only the sound you want comes through. 
  • Low-Noise Amplifiers: These are specialized components that filter out internal electronic noises, such as the faint hissing you might otherwise hear when no music is playing. 
  • Shielding: This technique blocks interference from other electronic devices like smartphones or Wi-Fi routers, preventing them from adding unwanted noise. 
  • High-Quality Capacitors: These components stabilize the electrical supply to avoid pops or hisses that can occasionally plague lesser systems. 

These features collectively contribute to a high SNR, giving you purer, more enjoyable audio. 

Why This Matters to Music Lovers 

If you've ever cranked up the volume only to hear annoying hisses or hums, you know how important clear sound is. A high SNR ensures that you can enjoy the finest details in your music, making each listening session a rewarding experience. 

What SNR Brings to Your Audio Experience 

A high SNR in your Audioengine system means you're not just hearing music; you're experiencing it in its fullest form, capturing all its emotional depth and intricate details. It's like the difference between watching a movie in high-definition versus standard definition. 

Breaking Down the SNR Numbers 

SNR is usually measured in decibels (dB). In layman's terms, the higher the dB number on the spec sheet, the clearer and more detailed the audio output. 


When shopping for a home music system, pay close attention to the Signal-to-Noise Ratio (SNR). It's not merely technical jargon; it's a crucial metric that directly influences the clarity and detail of your music. With Audioengine, you're not just buying a product—you're investing in a carefully engineered experience designed to elevate your listening pleasure. Trust that our engineers have meticulously focused on every detail because, for us, the true magic lies in the nuanced intricacies of the music.
