Taariikhda Harman ^(History)Curve^{(Harman Curve Technology)} Technology

Dib ugu noqoshada 2010-meeyadii, saynisyahannada Harman International (oo ay iska leedahay Samsung ilaa 2017) shaybaarka ayaa sameeyay daraasad ay ku ogaanayaan waxa ka dhigaya sameecadaha kuwa ugu wanaagsan. Qallooca Harman wuxuu ahaa natiijada dhowr daraasadood oo noocaas ah oo uu hogaaminayey oo uu daabacay injineer maqal ah Dr. Sean Olive , kaas oo helay dheelitirka xiriirka ka dhexeeya aragtida (waxa ay dadku jecel yihiin inay maqlaan) iyo cabbirka sayniska ee tayada codka taleefoonka.

Dr. Olive iyo cilmi-baarayaashiisu waxay daraasad indho la'aan ah ku sameeyeen 283 qof oo ku kala nool afar waddan iyo 11 goobood oo tijaabo ah. In kasta oo ka qaybqaatayaasha intooda badani ay ahaayeen shaqaale Harman , kooxda saynisku waxay ka taxaddareen inay gaadhaan kala duwanaanshaha jinsi, da'dooda, iyo waayo-aragnimadooda dhegaysi.

Daraasadu waxa ay ku soo gebagebaysay in habayntu aanay ku shaqayn sameecado-madaxeedka sababta oo ah anatomy bini aadamka. Hagaajinta ayaa sidoo kale ka duwanayd inta u dhaxaysa dhagaha-dhegaha, IEM^(IEMs) -yada , iyo dhegaha- dhegaha^(earbuds) . Sababta oo ah codka ay soo saaraan taleefannada dhegaha ayaa si toos ah ula falgala kanaalka dhegta iyo maqalka (ama pinna, qaybta muuqata ee dhegta bannaanka), halka dhegaha dhegaha ay la falgalaan oo keliya kanaalka dhegta. Laakiin sababtoo ah qof kastaa wuu ka duwan yahay, waxaa jira ku dhawaad ​​​​2 decibels farqi u dhexeeya sida aan u aragno dhawaaqyada dhawaaqa.

Waxaa jira afar geesood oo Harman ah oo kala duwan , mid walbana wuxuu u adeegayaa dookhyada kala duwan ee dadku ay yeelan karaan. Daraasadaha, cilmi-baarayaashu waxay u rogaan qalooca kasta iyadoo la raacayo doorbidka maaddooyinka imtixaanka intooda badan. Tusaale ahaan, daraasaddii ugu dambeysay, ee la sameeyay 2019, ayaa ogaatay in dadku ay rabaan inay maqlaan wax yar oo bas ah.

Xaqiiqooyinka xiisaha leh ee ay heleen cilmi-baarayaasha Harman waxaa ka mid ah in 65% maaddooyinka imtixaanka, maqal-yaqaannada, xirfadleyda, iyo dhageystayaasha maalinlaha ah, ay door bidaan sameecadaha dhegaha ee loo habeeyay qalooca Harman . Farqiga yar ayaa ahaa in ragga iyo shakhsiyaadka dhalinyarada ahi ay door bidaan bass badan, halka dumarka iyo dadka waaweyni ay door bidaan bas yar.

What Is the Harman Curve (And How Does It Improve Headphone Sound Quality)?

If you are interested in sound quality, you should learn about the Harman Curve. On the other hand, if you are looking for the perfect headphones, you must have heard the term Harman target curve. Maybe you have read reviews praising the headphones tuned to hit this target.

Truthfully, headphones tuned to the Harman Curve are not everyone’s cup of tea. This article will help you understand what the Harman Curve is and the science behind it. Then, you can make an educated purchase instead of blindly buying the headphones with the highest rating.

What Is the Harman Curve?

Audio tuning is one of the most critical factors in determining sound quality. Sound signature is tuning frequencies: bass, mids, and treble. The result of the frequency tuning can be represented as a frequency response curve. This curve describes the range of frequencies (and musical tones) the headphones can reproduce.

Headphone producers tune their products differently so they stand out from their competition. For example, some manufacturers prefer a flat and neutral sound signature, while others go for a V-shaped sound that is more fun.

One such curve is the Harman target curve. It is considered the best sound signature to tune your headphones, producing the best sound quality possible. There is a science behind it to back up this claim.

The History of Harman Curve Technology

Back in the 2010s, the scientists in the Harman International (owned by Samsung since 2017) laboratory conducted a study to find out what makes the headphones sound their best. The Harman curve was the result of several such studies led and published by audio engineer Dr. Sean Olive, who found the balance in the relationship between perception (what people prefer to hear) and the scientific measurement of headphone sound quality.

Dr. Olive and his researchers conducted blind studies on 283 individuals in four countries and 11 test locations. Although most of the participants were Harman employees, the science team was careful to achieve diversity in their gender, age, and listening experience.

The study concluded that the tuning for speakers didn’t work on headphones because of human anatomy. The tuning was also different between headphones, IEMs, and earbuds. This is because the sound produced by headphones interacts directly with our ear canal and auricle (or the pinna, the visible part of the outer ear), while earbuds interact only with the ear canal. But because every human is different, there is around 2 decibels difference in how we perceive sound frequencies.

There are four different Harman curves, each one catering to different preferences people might have. In studies, researchers tweak each curve according to the preference of the majority of test subjects. For example, the latest study, performed in 2019, discovered that people wanted to hear slightly more bass.

Among interesting facts discovered by Harman’s researchers is that 65% of test subjects, audiophiles, professionals, and everyday listeners, preferred headphones tuned to the Harman curve. The slight difference was that men and young individuals prefer more bass, while women and older people prefer less bass.

What Does the Harman Curve Look Like?

Here’s what the latest Harman Curve looks like:

The graph above displays the Harman curve for headphones and IEMs. Notice the difference. As explained earlier, the tuning differs depending on what anatomical part of the ear the device is interacting with.

Some evidence suggests that people prefer a flat and neutral sound. This might make you think the Harman curve would reflect this and look like a flat line. But as you can see from the graph above, it is far from flat.

Why is this? Due to our anatomy, when listening to the sound from speakers, a head-related transfer function(HRTF) for short comes into play. HRTF modifies or changes the frequency of a sound traveling through your environment, torso, and head before it hits your eardrum.

When listening to a sound through headphones, these frequency changes never happen due to the device’s proximity to your ear. A sound that leaves your headphone goes straight to your ear canal, and it is up to manufacturers to emulate the HRTF. If your headphones were flat and neutral, their sound would be extremely dull.

There is another reason why Harman’s curve is not entirely flat, and that is the fact that headphones are trying to replicate the sound as if it is coming from a room. After all, the most natural listening experience is from our environment. The source of the sound is rarely right up our ears. Harman curve amplifies the bass a little more to achieve the effect of a sound coming from a room.

Does Harman Curve Tuning Really Sound Better?

You must wonder how the Harman curve can predict what everyone likes to hear. We all have different tastes in music, genres, and loudness. Does one frequency response truly fit us all?

Some variations are explained by personal preference, but these are reported mainly by professional musicians with a trained ear. Personal preferences are much more subtle when it comes to non-professional listeners. Harman’s studies proved that most listeners have a similar taste for the sound coming from on-ear and over-ear headphones. The measurements conducted by scientists could predict people’s preferences with up to 86% accuracy. That percentage rose to 91% for in-ear devices.

You can try Harman curve-tuned headphones and hate the sound you’re hearing. You must understand that your ear needs time to get used to new tuning, especially if you have used poorly tuned headphones up until now. If you don’t like your Harman target tuned headphones even after some time, that’s fine. Harman curve is not the best solution for the sound quality that will please everyone. However, it is a great starting point, and a reference for sound quality backed up by science.
