Introduction

Most individuals spend hours a week wearing headphones, between music, games, audio clips, and unlimited online content. Unfortunately, if you’re considering acquiring new headphones, it’s not easy because of the diversity of types on the market, and you’ll find it hard to choose from all of those types.

In this article, he will tell us how to choose headphones, musician and university professor of music and sound technology, timothy Hsu, whose work is about studying the relationship between scientific, artistic, and subjective sound factors. Those three factors help us choose the right headphones, so how do we choose?

What’s The Headphones Sound?

Physically, the sound consists of air vibrations. These vibrations consist of high-pressure and low-pressure areas sound wave cycles.

If we count the number of cycles per second, we calculate the so-called frequency, or good tone, as high frequencies mean higher sound layers. The frequency measurement unit is hertz, to be 500-hertz frequency, meaning that the sound completes 500 cycles of high and low pressure per second.

The maximum pressure of the sound wave determines how loud the sound is. The higher the pressure, the higher the sound.

Near make sound, headphones turn electrical signals into those high and low-pressure cycles, which our ears interpret as sound.

Human Ear

Human ears are excellent sensors. The average person can hear a wide range of frequencies and tones, so how does the ear work?

When the sound enters the ear, the eardrum translates air vibrations into mechanical vibrations of the middle ear bones. Next, mechanical vibrations turn into vibrations that flow into the inner ear. Finally, the sensory nerves turn these vibrations into electrical signals that the brain interprets as sound.

The human ear can hear sounds extending from 20,000 to 20,000-hertz frequencies, although it cannot respond to those frequencies in the same way.

For example, if there’s a low-frequency tick sound on one side and a bird’s voice at a high frequency on the other, at the same high altitude as the first sound, you’ll feel that the horn is quieter than the bird’s. Usually speaking, the human ear is more sensitive to medium frequencies than low or high frequencies, which scientists believe has an evolutionary cause.

Most individuals don’t know that hearing sensitivity varies. They don’t need to think about it basically, simply because it’s the way they use hearing. However, headphones engineers should know how human perception of nature varies.

How Do Headphones Work?

Headphones of any kind are only small speakers. Simply put, it does the opposite of what your ears do, turning electrical signals from your phone, recorder or computer into vibrations in the air.

Most speakers remain made of four main components: a magnet that moves back and forth, a wire wrapped around an interest, a sound adapter that pushes the air, and the holder of this adapter.

When the direction of the electrical current in the wire wrapped around the magnet changes, the magnetic field around the wire changes in turn.
When an electrical signal passes a song, or any sound, into the headphone cord, that signal will change the current and move the magnet.

The magnets converted in and out, producing pulses of high and low pressure, are the music you hear.

Typically, the speaker is supposed to turn electrical signals from the source into audible sounds, but the laws of our physical world are specific. For example, some factors prevent the speaker’s inputs from matching its outputs, such as the size and type of magnets and adapters.

Several factors distort the signal, which explains the lack of ideal headphones.

The different quality of the high-priced speakers is because they distort signals in different ways.

When engineers work on new headphones, they consider how human hearing distorts the sound and the physical boundaries of any speaker.

Listener Preference for Headphones

The choice of new headphones depends not only on the complexities of the ear and the speakers themselves but also on the listener himself having a significant role in identifying good speakers.
Factors such as age, experience, culture. And music type affects the type of frequency distortion someone prefers.

Like anything else, your favourite type of headphones depends on a person’s taste. For example, some people prefer deep-rhythm headphones for hip-hop. Others prefer classical music, which will match fewer frequency distortions.

In addition, headphones can help hard of hearing people distinguish words. Supplying them at frequencies ranging from 1,000 to 5,000 hertz.

If you listen to hip-hop music using headphones for the hearing impaired, most people will agree that the results will not be satisfactory. Choosing headphones based on your use of them will save you a lot of trouble.
In the end, the science of headset design, the art of content presentation. And the user experience, all lead to a good headset.

With all available speakers, there’s only one guaranteed way to know if the speakers suit you or not? Choose a good song, put headphones on! If you feel excited and integrated. Then it’s your right choice.
