Keramički IEM po Meri

Every ušni kanal is different. Ovo nije platitude — to je an akustički reality with mjerljiv consequences. The length, diameter, curvature, and površina texture of your ušni kanal odrediti its resonant frekvencija, which tipično falls između 2.5kHz and 4kHz, and the magnitude of that rezonancija, which can premašiti 15dB. A universal-fit IEM inserts into this unique akustički okruženje with a generic shape, creating an unpredictable coupling između the nozzle and the canal that varies with insertion depth, angle, and tip compliance. The frekvencijski odziv you actually hear bears little resemblance to the frekvencijski odziv izmjeren on a test coupler. The Custom Keramika IEM eliminiše this variable u potpunosti.

The fitting proces zahtijeva an in-person appointment at our Quito headquarters. Ovo nije suggestion or a premium option — to je the only way to purchase this product. Tokom the appointment, an ekvatorijalni audiolog takes a full-canal silicone impression of each ear, duž with a head-related transfer function (HRTF) mjerenje using a binaural microphone array in our anechoic chamber. The ear impressions are 3D-scanned at 10-micron rezolucija and used to generisati the shell geometrija. The HRTF data is programmed into the inline DSP module, which applies a correction filter that kompenzuje for your specific ušni kanal rezonancija, pinna reflections, and interaural differences. The rezultat is a frekvencijski odziv at your eardrum that matches our reference target unutar ±0.5dB — not at a coupler, not at a simulated ear, but at your actual tympanic membrane.

The shells are machined from single-kristal zirconia keramika — a materijal with a Mohs hardness of 8.5, exceeding safir, and a density of 6.0 g/cm³ that pruža the same vibracija-damping benefits as the surgical čelik in our Equinox model but with superioran biocompatibility for prolonged skin contact. Growing single-kristal zirconia zahtijeva a skull melting proces in which powdered zirconia is heated to 2,715°C in a water-cooled crucible and allowed to solidify from the center outward, producing a kristal with no granice zrna, no porosity, and no unutrašnji stress. The proces takes 96 hours per boule. Each boule yields enough materijal for približno three pairs of IEM shells. The materijal cijena alone accounts for roughly a third of the retail cijena. We mention thnije as justification but as context for anyone who believes keramika IEMs should cijena less.

The ten drivers predstavljati every transduction tehnologija that currently exists in miniaturized form. Two electrostatic tweeters handle frequencies iznad 8kHz. Two planarni magnetski drivers cover the upper midrange from 2kHz to 8kHz. Four balansirani armaturni drivers manage the lower midrange and upper bass from 100Hz to 2kHz. Two 6mm dinamički pokretačs — yes, dinamički pokretačs in an IEM at this cijena — handle the sub-bass ispod 100Hz, because no other driver tehnologija can move enough air at these frequencies unutar the confines of an ušni kanal. The 24K zlato akustički bore tubes channel each driver's output to the nozzle aperture and are individually tuned by adjusting their length and unutrašnji diameter to align the faza response of all ten drivers at the nozzle exit. Zlato was chosen because it ne corrode, ne tarnish, and ne react with earwax. To je also beautiful, and at this cijena point, we nisu interested in materijali that are samo functional.
