  • Headphone extension will affect the sound quality What is the headphone extension cable?

    Most headsets now have a line length of about 1 meter, and some are only 0.5-0.8 meters long. When listening to songs, they often feel inconvenient because of short headset cables. Computer and small fever sound, speakers do not want to be placed next to the device? At this time, if you have a headphone extension cable, you can easily solve your troubles.

    We know that the main function of the earphone extension cable is to extend the length of audio equipment such as earphones. For example, if a desktop computer uses a headset, the headset cable is generally required to be longer. If the headset cable is too long, it is inconvenient to use a mobile phone MP3 and other devices. Has played a very good role in lengthening, unplug headphones can be used to mobile phone MP3 and other equipment convenient, plus the use of computers and other relatively long lines on the use of computers.

    To tell you the truth, if you use a headphone extension cord that doesn't affect the beats solo sound quality at all, it's impossible, because as long as there is a change in the sound quality, whether it's an extension cord or a patch cord, or even the adapter, it will have an impact. The key depends on you now. Headphones, front end. Therefore, it is not recommended here to use a headphone extension cord, no matter what brand of headphone extension cord is not a small damage to the sound quality. If you really want to use it, choose the earphone extension cable with better quality as much as possible. It is better to use a headset extension cable like a few dollars or even a dozen dollars on a certain treasure.

    Of course, this is only for people who have special requirements for sound quality. If there is no special requirement for sound quality, that would be fine. There is a proverb "Multiple Censers" that is appropriate for explaining the sound quality. Headphone extension cable, this more "Censer", in theory, is beats headphones on sale certainly the impact of the notebook output sound quality. Therefore, when the headphone line is long enough, try not to extend the line. If it is not to be used, it is also recommended beats headphones to choose a better quality extension cord to reduce the loss of sound quality to a level that can be perceived and distinguished by human ears.

  • Skull film characteristics, specifications and options

    Skull films are not as simple as they seem. In fact, it's not easy to make a good one. Therefore, high-quality cymbals are also very expensive. If you know the sounding principles of some cymbals, then finding your favorite cymbals will be easier. This tip describes the various characteristics of the cymbals and their tips. Like the drums, most manufacturers make unsuitable prices, and they also produce series of sedan films with different sound characteristics and different musical styles. The following will introduce the various characteristics of the sepals. Many cymbals have their own names, such as "Power," "Full," "Dark," and "Fast," and so on. These names all show their voice more or less. On the features, this will help you conduct an intuitive screening. Weight: A similar seizure on both sides, the heavier sounds sound slightly taller and slightly longer, and the response is slower. In other words, the heavier pieces need to be hit hard to get their better sound. Diameter: A larger beak is slightly lower in pitch and slightly longer in duration than a similar but slightly smaller diameter beak. Larger skeletons need more force to speed up their sound response. Shape: The radon has a slightly higher pitch and a slightly slower response than flat radon. Dimensions in the volume: This parameter affects the volume, the sensitivity of the sound, and the number of harmonics, where the number of overtones affects the fullness of the sound. The larger area of ??the cockroach makes the cockroach more responsive, making it easier to produce a louder and louder sound. The method of making the cymbals affects the sound. For example, in the process of hammering, the more rigorous the trace of hammering (the rules of dents on the surface of the cymbals), the more 锟斤拷rules锟斤拷 and clearer sounds will be produced. Conversely, irregular hammering marks (such as hand hammering) can produce dim, complex "irregular" sounds. Because the cockroach has only one part (only the sequins themselves), the production materials of cockroaches play an important role in determining their sound. There are many changes in the sound of a condolence. It can produce very sharp and clear sounds, and it can also produce very dim, thick, dry sounds. In general, louder music requires more clarity in the sound of a parallax, and the use of heavier paralysis favors this. A good test method is to first hit with the amount of force you would have played, then tap the beat. If you can hear independent beats from the beginning, you're right. The voices of parasols vary from high to low, from dry to delicate, from heavy to thin, from dignified to smooth, from solemn to warm, from calm to heated. The sound in the skull beats earbuds is compact and powerful. When you hit the rest of the cymbals, there is no sound in the cymbals. It's like hitting on the other side. When hitting the crickets, also listen to other parts of the crickets. Did they happen at the same time as the crickets? Still no matter how hard you hit, what you hear is just the sound of your voice. Many 18-inch and larger puppets can be used as craps for banging performances, as well as parades and tapping. The bash-attack sign can double as a smashing beats by dre and condolences, both heavy and light. If you can only buy one, it is a good choice. It is rare for a professional "thumping - tapping" chant. Many jazz bands and drummer drummers use their cymbals as both a hit and a tap. For this reason, they chose a relatively thin beryllium, which was made by irregular hammering. It can emit a series of harmonic harmonies. It can also emit a very clear sound in the case of a flick. However, this kind of embarrassment is not sold in the market as a punch-light.

  • In-ear headphones harm

    The damage of sound to hearing is called noise in medical science, and noise is divided into chronic sound injury and acute sound injury.

    Chronic sound damage. Refers to the slow progress of sensorineural hearing loss caused by long-term exposure to noise stimuli; this is called acute acoustic damage caused by a close-range explosion (such as a bomb bombing in a war), which is an instantaneous exposure to high-intensity impulse noise. caused. The damage caused by listening to headphones belongs to the former.

    The severity of noise damage to hearing is mainly determined by the intensity of the noise and exposure time. The greater the intensity, the longer the exposure time, the more severe it is.

    Therefore, in theory, the earphone's damage to hearing is mainly related to the volume of the listening music and beats headphones cheap the time of wearing the earphone, and has nothing to do with the way of wearing.

    An in-ear earphone user who listens to music for 3 hours a day and has a volume of 70 decibels per day is more likely to injure hearing than a normal earphone user who listens cheap beats to music for 5 hours a day and has a volume of 100 decibels. There should be no significant difference between the same volume of use cheap beats by dre and the same amount of time.

    According to the State's regulations on labor protection, the allowable standard for noise at eight hours is beats by dre 85 decibels, but it must not exceed 90 decibels.

    As Zhiyou said, the primary manifestation of noise snoring is tinnitus, followed by hearing loss, and can even cause dysfunctions in the cerebral cortex, autonomic nervous system, heart, endocrine and digestive system.

    However, the symptoms of hearing impairment can be fully recovered if they are detected early and intervened in time.

    At the same time, in-ear headphones can to some extent be able to isolate part of the ambient noise, that is, in theory, in-ear headphones can use a smaller volume and hear more sound details. However, this has not yet been heard of relevant clinical trials to prove it.

    As a headphone user for many years, I have used ordinary earbuds and earbuds. Now I use in-ear headphones.

    Compared with wearing comfort, it is slightly better than in-ear style. Because mid to high-end in-ear headphones come in a variety of sizes of rubber or sponge, there is always one for you. The ear canal almost feels no pressure when worn. The common earplugs wear for a long time, and the external auditory canal feels painful.

  • What are the characteristics of cheap beats by dre unilateral headphones?

    We all know the type of earphones, but we often overlook the other category of earphones, that is, unilateral headphones. What are the characteristics of this type of headset? Our common headphones have two, divided into two left and right channels, so that we can ensure that the sound we hear is stereo, and can distinguish the source of the sound's direction. Unlike a unilateral headphone, it has only one headphone. The usual design is the left channel, which is worn on the left ear. However, in this monophonic design, the sound is not accurate, so in recent years, many unilateral headphones will be designed as left and right channels combined headphones, that is, the left and right channels of the bilateral headphones are combined in one earphone. This combination ensures the accuracy of the sound and hears the details that the mono headphones ignore. However, even if the unilateral headphones are combined with the left and right channels, they are not stereo, but the sound and details of the bilateral headphones we use are all the same, but we cannot distinguish the direction of the sound. So unilateral headsets are often used for traffic functions, called traffic headsets. Because the operator needs to be able to cheap beats hear the sound in the headphones, but also to hear the outside world. If you design a pair of headphones, you can't hear the outside world.

    Unilateral headphones are also suitable for street use, because it is unilateral. When we go out to listen to music, in order to ensure the safety of travel, so the other ear needs to experience dangerous information about the external environment, it is suitable for sports family friends to use. When chatting with friends, you can also chat while listening to music. Some people think that unilateral headphones can damage hearing. For this argument, we must say: a loud volume, long listening to headphones, will cause a certain degree of hearing impairment, not a unilateral headset will definitely cause hearing impairment. After all, a unilateral headset beats headphones cheap does not always have to be on the same ear, but it can also be worn! However, if you use one ear to listen to the unilateral earphone for a long time, the two ears will have a certain sound when you remove the earphone for a brief period of time. Poor, but as long as the volume is small, this situation will not be obvious. Relative to forcing, unilateral headphones are still very popular with the traveler. Because the unilateral headphones are handsome, forcing the full.
