Microphone Statistics: New Recording Tech

Introduction

Microphone Statistics: A microphone is a device that transforms sound waves into electrical signals. There are various types of microphones, such as dynamic, condenser, ribbon, lavalier, and USB microphones, each with distinct features and applications.

Key components of a microphone include the diaphragm, capsule, transducer, output connector, and housing. When sound waves impact the diaphragm, they move, leading to alterations in electrical properties that generate the electrical signal.

This signal is then processed to produce audio output. Having a grasp of fundamental microphone principles is essential for selecting the right one for specific needs and achieving high-quality audio recordings.

Maximum SPL

• Microphones have a threshold for sound pressure level (SPL) beyond which they may distort, a limitation inherent to the microphone and not correctable through gain staging.
• Excessive SPL can even cause damage to some microphones, particularly ribbon mics which are particularly vulnerable to high SPLs.
• Additionally, certain microphones feature an Attenuation Pad setting (-10 or -20 dB) that can be utilized in loud environments to mitigate potential distortion.
• Maximum SPL levels typically correspond to a Total Harmonic Distortion (THD) level of approximately 0.5% to 1%.

Self-noise or Equivalent Noise Rating (ENR)

• Comparing microphones based on their self-noise level in dBA units provides a straightforward method, with lower dBA levels generally indicating better performance.
• Modern large diaphragm condenser microphones can achieve remarkably low self-noise levels as low as 5 dBA.
• Conversely, small diaphragm microphones tend to have higher self-noise levels, typically ranging from 12 to 18 dBA, while even smaller ones may reach levels between 22 to 27 dBA.
• However, the significance of self-noise level varies depending on the recording environment; for instance, noise levels exceeding 20 dBA may pose more challenges in quieter settings like classical music recordings. Thus, considering the context is crucial when evaluating the impact of self-noise on microphone performance.
