Sanmenxia where there where show the the monopoly wholesale selling recording microphone pickup in broadcast Quotations room vocal language classes, and often use two types of dynamic microphones and condenser microphones. Rugged dynamic microphone, high sensitivity, good point, picked up the sound of clear, pure, soft Jiaming Yang 1503 +71780 +75 www.69139139.com 1399 +229 +631 Milan sun, Zheng * City Market Building 5, Unit 2 208, frequency response range of 40 Hz ~ 16 kHz; condenser microphone the sound quality is good, high sensitivity, the sound picked up plump, bright, subtle, subtle, frequency response of 20 Hz-18 kHz people ears to hear the band. Condenser microphone directivity characteristics, such as NeumannU89i microphone, a total of five point features to choose from: omnidirectional, semicircle, heart-shaped, super-cardioid and figure eight can be used in a variety of recording conditions. Recording of the broadcast language class show host in the form of the main indicators, clarity, mostly choose heart-shaped, super-cardioid dynamic microphone or a capacitor microphone. The heart-shaped directivity characteristics is unidirectional pickup, pickup only in front of the sound. When the vocal mouth alignment the microphone center axis angle "0 °", the best output frequency response of the microphone, in his speech when the speaker face, neck swaying up and down shaking, mouth deviation from the central axis of the microphone sound sound energy will drift or attenuation. 8-shaped directional microphone is bi-directional characteristics, the microphone on the front and back of the sound can be picked up closing interview programs can be used for pickup. Jiaming Yang 1503 +71780 +75 www.69139139.com 1399 +229 +631 Milan sun, Zheng * City Market Building 5, Unit 2, 208 omni-shaped microphone sound in the range of 360 ° can be included, such as Neumann U89i microphone pickup area, the pickup can be used for a larger number of occasions. Recorded broadcast language class program, not only be familiar with the directional characteristics of the microphone, but also to adjust the distance between the good microphone and the sound source the pickup distance affect the tone of the sound, but also related to the reverberant ratio between the direct sound, "straight mixed than" affect the clarity of the sound. In other words, the microphone and the sound source is too close, low-frequency strengthen sound distinguish high levels, there is no sense of space; too far away from the microphone and the sound source, vocal clarity, send virtual sound, direct sound is weakened, poor intelligibility. The recording proved: good indoor frequency response equalization, a uniform distribution of sound power pickup conditions, repeatedly to adjust the tilt angle of the microphone, the microphone pole height and the distance to the sound source, the the reverb radius of and placed in the sound field within , which is the best angle of the microphone picks up sound, but also the effective distance of the picked-up sound, it is guaranteed sound clarity, a degree of integration. Jiaming Yang 1503 +71780 +75 www.69139139.com 1399 +229 +631 Zheng * City Market Milan sun Unit 2, Building 208 undeniable factors affecting speech intelligibility many, such as the voice of the "pop" sound. Spray microphone phenomenon often exist, because the microphone diaphragm is subjected to vibrations when puff sound is the articulation too loud, you will hear the sonic impact of air. If this happens, slightly widening pickup distance, slightly deviate from the direction of the impact of air, or open the microphone gain attenuation switch, so as to eliminate distortion, reduce the gain to improve the sound quality purposes. The people sound too large there is often a small problem. When two or more sound sources simultaneously sound, the feeling of the people there will be sound in the auditory sample sizes. Usual speech of the people, everyone has their own vocal characteristics, has its own tone, pitch, homophonic sound high and low, strong or weak, whispering the sound energy is 20-30 dB loud speech 60dB, of voice audio bandwidth range between 60 Hz-10 kHz. So, people in his speech loudness inconsistencies may pickup microphone placed in the recording angle, orientation and pickup distance, it may be the quality of the sound source, the characteristics of the problem of inconsistent size and acoustic frequency. Actual recording cao for each band and peripherals adjust the sound frequency mixer, an important means to ensure balanced audio. In the the broadcast of Quotations room or the news studio, have equalizer, limiter, effects, frequency shifter hardware peripherals, which beautify the sound color, clarity of language class program recording means.
