1: How do ordinary consumers distinguish quality and effect when purchasing microphones?
1. From a visual point of view, whether the product design has a unique design style, or has the same appearance as many similar products on the market, if the product has its own design style and meets the preferences of consumers, it is a high-quality indicator.
2. The material and production process of the microphone are generally all metal, metal-plastic mixture and all-plastic. However, it should be determined according to the design style, cost and process difficulty of the product. The average consumer can define the texture of the product through the actual use experience.
3. The microphone button is considered to be a product of relatively good quality, with relatively smooth operation, good tactility and high operational reliability.
4. As a consumer, judging the sound quality of the microphone mainly depends on the sense of hearing. Whether the amplified sound is good or not, whether the sound is easy to sing and say, that is, whether the sound is good or not, are all very important criteria.
5. With the stability of sound transmission and the effective transmission distance of the microphone, consumers can choose suitable identification products according to their own needs. Here, the farther the transmission distance is, the better, but within the effective use distance of the sign, the signal is uninterrupted, without interference, and without noise, so it is an excellent product.
2: Which indicators of the microphone are professional users more concerned about?
1. Dynamic range
Generally speaking, the small and loud sounds that can be heard by the human ear are between 0 and 120 decibels, and the microphone also has a recording volume range, which we call the electrical frequency difference, which is the dynamic range. The microphone parameters are generally marked as Max SPL and E.I.N (sound pressure and noise floor). The latter is the dynamic range of the microphone after subtracting the former. For example, maxspl is 130db spl and e.i.n is 16db, so the receiving range is 114dB. If the noise floor is too high and the sound is weak, it must be very close to the sound source, otherwise it will not be recorded below the noise floor at all, otherwise it will not be recorded at all. So the wider the dynamic range the better, but the price may be higher.
In fact, when recording, challenging the edge of the dynamic range is very risky. So, from a more practical point of view, the dynamic range actually determines the sampling realism of the sound at high fundamental pressure and near the noise floor. You can think of this as the dynamic range of the image. When you shoot with the camera and phone at the same time, the details of the highlights or shadows are incomparable, and the sound is also focused on dynamic range. If the dynamic range is not good, the sound may be distorted if the sound is too loud, and the sound will be covered by the background noise if the sound is too low, and the post-processing will be troublesome.
