![]() ![]() 4Ĭurrently, musicians using 432 Hz, as well as opera singers in the 1980s, declare that when musical instruments are tuned to 432 Hz, music becomes “hotter” and the perceived volume seems higher at parity of Decibel (dB). The frequency of 432 Hz music, as already mentioned for 440 Hz, refers to the value of the note A4 (LA3) of the central octave of the piano, which is taken as a reference to tune all the other notes in the time system. 7 The transposition process can also be viewed in different videos on the web (YouTube). The transposition of music from 440 Hz to 432 Hz is obtained by imperceptibly slowing down (by 32 hundredths of a tone) the execution of a song originally tuned at 440 Hz, using music editing software. Furthermore, on the web (YouTube) there are music tracks that have been transposed to 432 Hz from their original 440 Hz tuning. The 432 Hz tuning is sometimes used in the New Age genre (meditation music) 4 and by some musicians. So, nowadays, all the music we generally listen to is tuned to the 440 Hz frequency. 4 This frequency value was established in the 1950s 5 and confirmed in 1975 as the standard tuning for music worldwide. The current reference frequency for tuning musical instruments is 440 Hz, which corresponds to the musical note A4 (LA3) in the central octave of the piano. Specifically, the frequency values determine the tonality and influence the timbre of the sounds. The Hz express the cycles per second (1 Hz = 1 cycle per second). 1, 2įrom the point of view of physics, music is made up of sounds that are generated by waveforms whose frequency is expressed in Hertz (Hz). The whole history of human civilization shows evidence of connections between music and physical and mental healing. different pads, modifications etc.).Music has always been perceived as having special healing powers in people. Any changes or modifications will be stated in the measurement entry itself (e.g. All headphones are measured stock unless otherwise stated. The measurements are performed with the assumption of a “perfect seal”. Placements that results in abnormal rolloff are scrapped and re-done until a proper seal is achieved.ħ. If you find issues with my measurements, it can be any of the following:ī) Broken/malfunctioning units (in a way that is not immediately obvious)ĭ) Measurement error (yes, I am human, I make mistakes sometimes)Ħ. Unit variation is a thing. I do not control what demo units the companies provide to me or to their distributors (where I usually do measurements). If not for the graphs, one can also take this database as a list of headphones I’ve tried and auditioned, and the graphs simply being proof of it.ĥ. 99% of the headphones I’ve measured, I have listened to as well. I get that certain people like to paint me as some sort of objectivehead figure where all I do is look at graphs and determine quality sorely off of said metrics. Measurements are meant to complement subjective impressions, not form the basis for them. ![]() For additional target curves, the Graph Comparison Tool has them available.Ĥ. All headphone measurements are compensated to the “IEF Neutral” target curve by default. Flat on the graph DOES NOT MEAN flat in real life. The fact that headphones bypass the head necessitates higher SPL in the 2-5k regions as compensation (see: Diffuse Field, Head Related Transfer Function, Harman Target).ģ.1. This means that measurements in this database are directly compatible with target curves like KEMAR Diffuse-Field and the Harman Target, both of which are derived from GRAS rigs.ģ. Measurements in this database are done on a GRAS 43AG-7 and so conform to the standards laid out in IEC60318-7. ![]() It’s not going to tell you if it’s good ice cream, but at least you have a way of finding out if it’s the flavour you want.Ģ. The FR is like the branding at the side of the tub telling you the flavour of the ice cream. A Frequency Response graph is not in any way an indication of good sound quality. Think of it as flavours, like in ice-cream.
