What are the specifications of headphones?

If you are interested in knowing the type of headset (for example, “How it works” or “Design”, close or open, etc.), you can read the appropriate manual, as this special article will be more devoted to topics, through boxes or web- sites. The term “measuring” headphones at the bottom. Having said that, these words can be important, and there are several “specifications for headphones for technical terminology,” which we hope will help us complete this journey, some of which are more important than others. Here is our list and links to specific terms, if you are considering specific specifications. Otherwise, please do not hesitate to read.

Now I know what you’re thinking. It’s too much, I just want to know what term I need to find, so my music sounds good? Well, if you are looking for really high quality headphones, then you should be familiar with one of these headphone features. Understanding the meaning of these conditions will give you the tools you need to ensure the highest quality sound for your device. So, let’s solve some of these secrets.

Drivers

What is a driver? Simply put, the headphone driver is just a magnet, some voice coils and aperture that can receive electrical signals from your device and convert them into sounds that your ears can receive. They come in different sizes and styles. Often, large drivers mean that you can manage them, but not scale them. While larger discs will give you lower frequencies at lower frequencies, sound will begin to decompose at higher frequencies. Think of it as a big subwoofer in a car or home theater. McGregor vs Khabib Live Streaming Online They have huge drivers and work well in explosions or 808 drums, but when you hear sounds or violins, the sounds are low or distorted. This is due to the fact that when the high-frequency sound passes, the actual surface of the diaphragm changes its shape, and for large drives the frequency response (which we will discuss later) becomes irregular and causes distortion. Smaller discs can also create very good bass levels, and some up to 6 mm in size provide deep bass without distorting higher frequency sounds. Drives come in different types, with balanced reinforcement, static, flat magnetic and dynamic.

Sensor technology

The headphone specifications vary with the brand, and the sensors are not really one of the products that you should be an expert to buy a good headset. All converters provide you with an electronic signal that a CD or phone will create and convert into sound waves that your ears can receive.

Frequency response

Frequency response is one of the technical terms with which you need to familiarize yourself with the specifications of the headset. The frequency response is the range in which the headphones reproduce the sound. Their spectrum ranges from high-frequency high frequencies (30,000 Hz) to low-frequency bass (5 Hz). Basically, the sounds of bass, treble and midrange that you hear in your headphones are similar to the acoustic system in a car. You can use large speakers for bass, midrange for midrange and smaller loudspeakers for high frequencies. In headphones they are usually combined into one speaker.

In general, the range is from about 5 Hz to 40,000 Hz, although most headphones try to stay in the range of 20 to 20,000 Hz. Noise above 20,000 Hz is not always detected for some people, and the noise level is below 18 Hz, and your eardrum does not sound as strong as it seems. Because not all companies mark their columns as the same, you will see something like “dB” plus / minus. Do not worry, all this means that the sound is perfect for the original recording in the entire frequency range and how accurately reproduced. This is sometimes called “flat” sound. The closer the number to zero, the closer the headphones

impedance

When it comes to headphone specifications, impedance is another technical term that you want to know when buying a new package. When the company lists this rating, you will consider it as a Greek letter to Omega and call it “om”. In short, this rating is expressed in the range from about 2 ohms to over 600 ohms, which basically means that you need to increase the volume to get the desired listening level. The higher the ohms, the more power the device needs to reach this level. Previously, the home stereo system could output enough power to control 4-8 ohm speakers, and it was very expensive. Today you can find high-impedance headphones, which take up only a fraction of the time. However, many headphones with a higher resistance require that the headphone amplifier fully activate them.

sensitivity

Sensitivity is another technical term for specifying headphones that you want to understand. In short, it depends entirely on efficiency. How effective is the conversion of electronic signals from CDs or mobile phones to undistorted sound waves. Sensitivity levels are listed in decibels (dB), and most headsets have a range of 85 to 105 dB. Anything above 110 dB will damage the human ear in a short time. This should be taken into account when the sound source is less than an inch from the ear.

Low-sensitivity headphones require more power from the device to provide you with high-quality sound, but in return they last longer than headphones with high sensitivity. High-sensitivity headphones provide better performance at lower power, but when you turn the volume up to maximum distortion, it becomes a factor, and headphones (and your ears) can be damaged over time.

Total Harmonic Distortion (THD)

Another term that you do not need to be an expert is full harmonic distortion or THD. Your device and headset have different levels of THD and can actually measure them in different ways. THD refers to the comparison of signals from the input and output of the device and is expressed as a percentage. The actual percentage is measured from the base test, and zero is excellent. As for the specifications of headphones, the human ear is unlikely to notice a complete harmonic distortion, especially if you think that most headphones have a rating of 0.1% to 0.005%. Even with noise-canceling headphones, you can still get sound from the outside world. For complete harmonic distortion, the lower the better. Expect as close as possible to zero.

Sound pressure level (SPL)

The sound pressure level is related to the sensitivity level we discussed earlier, so we will not spend too much time here. Although the sensitivity is completely dependent on efficiency, measuring the sound pressure level (or SPL) is the maximum dB level of these headphone outputs. When you see this rating, it will be displayed as dB SPL / mW or dB / mW, and today most headsets and headphones will be in the range of 85 to 125 dB SPL / mW.

Maximum input power

Now that our mind is getting rid of all this complex information, we will now begin to integrate these headphone specifications to help you better understand the importance of maximum power when searching for new headphones. The maximum value of the input power is the power that the headset can support, and is expressed in kilowatts (or milliwatts). Some companies do not list the maximum input power in a headset package or specifications, but you can find this information on the company’s website. The user guide for your source (mobile, amplifier, TV, etc.) should also provide you with this information. This is a coincidence when buying a new headset. Most phones produce about 1 W (0.001 mW), and a headphone amplifier can raise this number to 3 watts (0.003 mW). 3W is a lot of power, and if it does not fit, it’s easy to damage the headphones. Ideally, you need to find the speaker, which is closest to the maximum input power of the source.

Noise attenuation

The attenuation of noise is defined as the loss of acoustic energy. When sound waves pass through space and come into contact with other materials along the way, it loses its energy. For headphones, we are talking about structural materials used to reduce noise and absorption outside the headphones themselves. In most cases, this information is not very useful, and the attempt to find soundproof materials used by the company may be useless. Foam and cotton are the most common, but some companies use acoustic glass for soundproofing.
