Headphones are one of our common audio output devices, which enable us to better hear audio signals and enjoy a better music experience. The parameters of headphones are directly related to their sound quality and effect, especially in recording, music production, and professional occasions, it is even more necessary to consider the parameters of headphones. The following are some common parameters of headphones:
1. Frequency response: refers to the response of headphones in various frequency bands, usually expressed in Hz (hertz). The wider the frequency response range, the better the sound effect of the earphones, and the better the details of the music.
2. Impedance: Simply put, it is resistance. The higher the impedance, the more energy is required for electroacoustic conversion, and a stronger driving force is required to drive the earphones. Therefore, a more powerful audio device with a stronger power supply is needed to drive the earphones. The impedance value of headphones is generally between 8 and 32 ohms.
3. Sensitivity: Indicates the sensitivity of the earphones to sound. The unit is decibels (dB). In theory, the higher the sensitivity, the greater the loudness. However, in reality, the sensitivity of different earphones needs to be analyzed in conjunction with other parameters.
4. Tuning style: The tuning style of headphones is usually divided into several types, such as flat, V-shaped, and U-shaped, with different styles adapting to different music styles. Specifically, the calm style is suitable for playing electroacoustic instruments, the V-shaped style is suitable for pop and electronic music, and the U-shaped style is suitable for rock and heavy metal music.
5. Unit: Also known as headphone driver, it is the core component for converting audio signals into sound. Common earphone units include moving iron, moving coil, flat coil, etc. Dynamic iron has good sound quality and scalability, making it a commonly used unit for high-end headphones; Dynamic sound quality is smooth and soft, suitable for basic music enthusiasts; The flat coil unit depicts a more delicate sound quality and is a necessary unit in the field of professional auscultation and photography.
6. Wearing comfort: I believe many people have experienced the problem of ear soreness after wearing headphones for a long time. Therefore, the comfort of wearing headphones is also an important parameter. Wearing comfort is not only related to material and weight, but also influenced by various factors such as wearing method and wearing area.
The above are some common parameters of headphones. Understanding these parameters will help us choose headphones that are more suitable for ourselves and improve listening performance.
