Precautions for use of earphones

Precautions for use of earphones

Matters needing attention when using in-ear headphones.

Because headphones are closer to the inner ear tissue than normal external noise; All users are required to take necessary protective measures. Studies have shown that pleasant music causes less hearing damage, but long-term exposure to high-decibel sounds, either music or noise, can cause hearing damage. Noise-induced sensory nerve hearing damage occurs in the inner ear, when high-energy sound waves shock fluid in the cochlea, overstimulating and causing cell death. Hearing damage can build up over time, and long-term exposure to noise, even for a short time, can cause hearing loss.

Research published in the journal of the American medical association in 1998 and conducted at shanxi medical university in China showed that prolonged exposure to high noise levels had a negative effect on hearing.

In-ear headphones supplier China shares that when using earphones in the street, in addition to the hearing impairment caused by the need to increase the volume, it is easy to lose the alertness of users to peripheral sounds and increase the chance of danger. Children should not use earphones.

Ways to improve your headphone space

Ways to improve your headphone space shared by Wireless Sports Earbud factory.

The spatial aspect of the headphones has been unsatisfactory (the other is low frequency), which should be said not to be the drawback of the headphones, but the features of the headphones. A headphone is a pair of small speakers on either side of the head (which is how the headphone was originally created), and the sound field is naturally in the head. Modern recordings tend to use multiple microphones, and there are few single point recordings and head recordings, which is another reason for the poor spatial sense of earphones. In order to improve the "head-to-head effect" and make the earphone hearing sense more in line with people's physical and psychological characteristics, spatial simulation is required. There are three main methods: crossfeed, in-front localization and surround. The first two methods are used in two-channel stereo system and surround sound is used in multi-channel system.

1. Each feed

Such as AKG K1000, Precide Ergo, Jecblin Float, they use small sponge to keep unit outside the ear at a distance, so that each ear can hear the voice of the other side of the unit, the feed each other with the voice of the auricle positioning function, sound field will be more, depth, K1000 was able to adjust the Angle of the unit to adjust the space effect.

2. Positioning forward

For example, Vivanco SR2000IFL, the general earphone unit directly emits sound to the listener's ear, Vivanco SR2000IFL unit is placed in front of the ear to simulate the way of sound transmission during daily listening, the K1000 also has this function, and some models of SONY and STAX also adopt this design.

3. Surround sound

3-1 four-channel system

For example, AKG K290 has two drivers per side unit. When fed to its four-channel signal, it can get a better sense of space than two-channel signal. The specific effect is related to the design.

3-2 Sennheiser Surround headphones

Its surround sound part is independent and hangs on the shoulder. The main channel earphone is still the traditional way and the head can be moved at will. Now there are products for PC.

3-3 simulate surround sound

The surround sound effect is simulated by surround sound processor. The earphones buy from Wireless Sports Earbud wholesale use traditional dual-channel earphones, and there are many products in the market using this technology. Sennheiser has similar products, such as Lucas and DSP360; Dolby has a new Dolby Headphone based on the Dolby ac-3. These systems require a higher-end earphone fit with an excellent acoustic design to get the most out of them.

3-4 vibrating earphone

Panasonic has this product, which USES a vibrating unit that vibrates with a low-frequency signal to make it feel low-frequency, which is actually a way to improve the way headphones can only hear and not feel low-frequency. But people experience low frequencies through their gut and uhf through their skull, which is a little bit of a thirst quench.

Why don't headphones and speakers replace listening systems?

In-ear Metal Earbuds manufacturer shares that there is often a high level of concern about microphones and voice recorders, but a lack of attention to the monitoring system.

Listening system is another pair of ears of musicians, our music works must be based on it as a reference to achieve, its importance can be imagined.

Why don't headphones and speakers replace listening systems?

What are good listening environment conditions?

1. Stable balance from treble to bass

Never too strong or too weak in either range, try to keep it as smooth as possible at the same volume.

2. Easy to find flaws resolution

Small noise and tonal differences are not drowned out by other sounds and can be clearly judged.

3. No exaggeration or short stature

It can correctly judge the "size" (three-dimensional sense, depth) of the sound field built after mixing all the materials.

Why don't headphones and speakers replace listening systems?

Recording studio for signal monitoring tools are "listening speakers" and "listening headphones" two categories. Due to its characteristic of faithfully presenting the original appearance of sound, it is mainly used for sound playback in the recording studio to provide audio reference for producers. It is not suitable for listening to music, and its real mission is to find defects and problems in audio signals timely and accurately. For this type of device, we look at factors such as the accuracy of sound reduction, auditory fatigue, and power.
