Indicates the frequency range that a microphone can capture and is expressed in Hertz (Hz). The more balanced the range, the more natural and clear the sound.

Usage examples:

• 100 – 10,000 Hz to 200 – 12,000 Hz: Emphasis on speech intelligibility, with limited low and very high frequencies.
• 50 – 14,000 Hz to 80 – 16,000 Hz: Balance of volume and clarity. Ideal for live performances and dynamic microphones.
• 40 – 15,000 Hz to 50 – 18,000 Hz: Rich, natural vocal sound. Suitable for podcasts, radio, and streaming.
• 20 – 18,000 Hz to 20 – 20,000 Hz: Full spectrum with high detail and "air". Ideal for studio recording.
• Below 20 Hz & above 20,000 Hz: Extended technical range for specialized studio applications.

Indicates the difference between the useful signal and the microphone's noise. The higher the value in dB, the clearer the sound. A microphone with a low SNR may sound “noisy,” especially in quiet environments or when recording low-volume sounds. On the other hand, a high SNR means that noise is minimal compared to the sound you want to capture, offering a more professional, clear, and detailed result—ideal for studio, vocals, or high-quality recording.

• 35 – 60 dB (Low SNR): Noticeable noise is present. Suitable for casual use or loud sources.
• 60 – 90 dB (Medium SNR): Good signal-to-noise balance. Suitable for live performances and general use.
• 90 – 110 dB (High SNR): Very clear signal with minimal noise. Ideal for studio, vocals, and high-quality recording.
