Monitor headphones are headphones that have not been rendered with timbre, as opposed to HiFi headphones. By using monitor headphones, you can hear the closest approximation of real, unmodified sound quality. It is widely used in recording studio, dubbing room, television, radio and MIDI studio and other fields.
Monitor headphones should have the following characteristics: first, the frequency response should be wide enough and fast, so as to ensure that the signal distortion within the frequency band to be listened to is as small as possible, and the ability to clearly reflect the sound characteristics of the listening objects; Second, it is strong and durable, easy to repair and maintenance.
HiFi (High fidelity, is defined as a playback sound that is highly similar to the original sound）Headphones are aimed at the field of civil consumption, and are used to appreciate music, listen to radio and watch movies. They have the following characteristics: first, the frequency response should be as flat and wide as possible, so as to enjoy all kinds of music with good results. Second, it has high efficiency to adapt to the earphone amplification circuit with small output capacity of civil audio equipment. Third, the quality of light, wear to be comfortable.
From the perspective of usage, monitors headphones are divided into studio monitoring, broadcast monitoring, sound amplification monitoring, special (special) monitoring, etc., among which studio monitoring is divided into simultaneous (on-site feedback) monitoring and contraction mixing monitoring.
Because of the function of listening in the earphone to restore the original sound, it can better help wearers to distinguish the high and low sound, accompaniment sound and so on. It is suitable for singers and announcers to wear it so as to correct their own voice and reach a more professional level.
Classification of USES
1. On-site return
In general, live return is to send the accompaniment music, beat or music melody to the recorded singer, performer, etc., just like singing karaoke without the original music. The purpose is to let each singer and player hear the rhythm and music clearly and coordinate the recording. Therefore, the requirements for this kind of earphones are not high, but the precondition is that the earphones should be closed or semi-closed, because the capacitive microphone used for recording is highly sensitive, and some weak details will be picked up, including the sound leaked from the earphones.
2. Shrink and mix monitoring
Shrinkage and mixing listening is the highest requirement for the sound of the headset. It requires that all sounds can be truly restored as far as possible, with as little noise staining as possible and the sound location close to the scene. This is also the effect pursued by the fever headset, so this kind of headset can be used as the fever headset.
3. Broadcast monitoring
Radio monitoring is mainly required in the broadcast of the radio program, the program host and guests, as well as the director, production director and other real-time monitoring. Speaking of real-time, actually there is also delay, because many radio stations adopt the form of live broadcast, in order to prevent accidental and some conversations that are not suitable for public broadcast (such as swearing, aggressive words and sudden reactionary remarks, etc.), it needs to delay broadcasting for several seconds, which is operated by special broadcast delay device. This broadcast requires listening headphones to have a very high language clarity and intelligibility, which can filter out the noise in a speech that affects intelligibility and intelligibility, such as low-frequency interference, telephone noise, etc. Of course, there will be an equalizer specially prepared for the headset in operation, but the quality requirements of the headset are relatively high. Because the sound of these earphones is relatively dry, the language definition is relatively high.
4. Customized in-ear type
Custom in-ear monitor headphones (IEM) relative to the general and sound box type stage and foldback listening has obvious advantages, the first is sealed performance is good, effectively isolate external noise, the second is the transient response is fast, real-time capture the tempo and acoustic signal, three are closely embedded triangle nest of human ear and ear cavity, wear even if action is not easy to fall off. Today’s singers perform live using ear monitors rather than floor wedges. That’s why singers use ear monitors instead of floor wedges to perform live.
5. Sound amplification monitoring
The requirements of sound amplification monitoring on headphones can be high or low. As long as the listening headphones of ordinary dance halls can clearly listen to the music and language content played, the proportion of reverberation and human voice that are relatively satisfactory can be adjusted. The monitoring can be accurate, and low-end headphones such as Sennheiser HD433 and AKG K70 can meet the requirements. DISCO ballroom USES the close type that single ear or double ear listens on earphone commonly, requirement low frequency is strong, sound pressure is big, sound insulation ability is strong, firm and durable, wait for a few models such as SENNHEISER HD25SP, PIONEER DJ-1000, Panasonic. For concerts and high-end acoustic amplification occasions, the requirements for monitoring headphones are higher, but generally the main listener is a professional listener speaker, the headset is generally used as an auxiliary listener, it is ok to use high-end closed or semi-closed headphones, such as AKG K240M, K240DF, SENNHEISER HD250, HD265, HD25 and so on.
6. Dedicated monitoring
This kind of monitoring can be found everywhere around us, such as pager miss pager of pager station, telephone operator of telecommunication bureau, etc., what they wear is the enclosed monitoring headset with microphone, which requires a high degree of language intelligibility. There are also aircraft pilot monitoring, car driver scheduling monitoring, tank crew command coordination monitoring, sonar monitoring in the submarine, etc. According to different needs to choose different special headphones.
