Final Audio TONALITE Trådløse aktive støjreducerende øretelefoner (Åben æske)

TONALITE: Verdens første øretelefoner med personlig klangfarve

Vi hos final er stolte af at introducere verdens første øretelefoner, der kan personliggøre klangfarven baseret på præcise målinger af hver enkelt brugers anatomiske træk – guidet af en dedikeret app. Ved at udføre detaljeret analyse og akustisk simulering af lytterens individuelle øre- og hovedgeometri gengiver TONALITE naturlig klangfarve med enestående troværdighed, hvilket giver brugerne mulighed for at opleve deres yndlingsmusikoptagelser så tæt på kunstnerens eller producentens intentioner som muligt.

Tidligere tilgange til lydpersonalisering, hvad enten det er i akademisk forskning eller kommercielle applikationer, har primært fokuseret på at forbedre den rumlige oplevelse af lyd, hvilket muliggør en mere præcis opfattelse af retning og afstand. Sådanne metoder gavner dog kun indhold med fordybende binaural lyd, som typisk gengives fra tredimensionel multikanal-lyd eller optages ved hjælp af en HATS (Head and Torso Simulator).

I modsætning hertil, når man lytter til musik og de fleste hverdagslige indhold, der er optaget og mixet i et stereofonisk højttalermiljø, specifikt to-kanals stereo, er naturligheden af klangfarven det, der virkelig betyder noget. Uden den, uanset hvor avanceret den rumlige gengivelse måtte være, så er musikkens følelsesmæssige påvirkning uundgåeligt formindsket.

Af denne grund er final banebrydende inden for Digital Twin Audio Simulation (DTAS), en ny tilgang designet til at levere den mest naturlige og følelsesmæssigt engagerende lytteoplevelse for den musik, folk nyder hver dag.

Klangfarve: kernen i musikalsk nydelse

Klangfarve definerer musikkens overordnede karakter ud over dynamik, melodi, harmoni og rytme og er direkte forbundet med komponisters og performeres udtryksfulde intentioner. Det refererer til lydens tonale kvaliteter, der adskiller en kilde fra en anden, uafhængigt af tonehøjde, lydstyrke eller rumlige attributter. Selv instrumenter af samme type kan producere forskellige klanglige indtryk afhængigt af producenten, de anvendte materialer eller subtile variationer i konstruktionen.

Al musik er skabt med klangfarve som et centralt element. Selv med identisk rytme og melodi kan en fremførelse af et stykke med forskellige instrumenter eller teknikker dramatisk forvandle lytteoplevelsen. Derfor vælger komponister omhyggeligt instrumentering for fuldt ud at formidle deres værkers udtryksfulde budskab, mens instrumentmagere håndværker hvert instrument for at opnå distinkte klanglige identiteter. Performere forfiner til gengæld deres teknikker for at kommunikere musikalsk intention så trofast som muligt. Når musik optages, omdannes disse udtryksfulde nuancer til elektriske signaler, ofte under tilsyn eller feedback fra komponisten, performeren eller producenten for at bevare den tilsigtede klanglige karakter.

Evnen hos øretelefoner til trofast at gengive den klangfarve, der er indlejret i disse optagede signaler, er derfor afgørende for selve essensen af den musikalske oplevelse. Ved at udnytte vores Digital Twin Audio Simulation (DTAS) opnår TONALITE naturlig og præcis klangfarvegengivelse, som konventionelle tilgange ikke kan opnå. Dette gør det muligt for lyttere at opleve musik i dens reneste form, fri for konventionelle audioevalueringsmetrikker, og at høre fremførelser, som de var virkelig tilsigtet.

Personaliseringsteknologi

Digital Twin Audio Simulation (DTAS)

Den DTAS implementeret i TONALITE er baseret på finals proprietære forskning i personlig klangfarve. Det bruger fysiske data om brugerens kropsform, opnået via en smartphone, og behandler disse data gennem finals unikke auditive model. Denne model udleder de akustiske karakteristika, der gør det muligt for hver enkelt person at opfatte den mest naturlige klangfarve, som derefter implementeres direkte i TONALITE-øretelefonerne.

I hverdagen stammer den naturlige klangfarve, vi opfatter, fra de lydbølger, der når vores trommehinder, som akustisk påvirkes af de unikke konturer af vores hoved, ører og overkrop. Men fordi øretelefoner leverer lyd direkte ind i øregangen, udelades de naturlige akustiske effekter af hoved, ører og overkrop på lydbølgerne. Som følge heraf kan klangfarven adskille sig fra den naturlige lyd, du opfatter i hverdagsmiljøer.

For at løse dette scanner DTAS din fysiske form for at skabe en 3D-model af din overkrop, kaldet “ Acoustic Avatar®, ” som repræsenterer dine unikke akustiske karakteristika. Derefter simulerer DTAS de akustiske effekter af din unikke kropsform gennem finals proprietære auditive model, en matematisk repræsentation af, hvordan den auditive cortex opfatter klangfarve, for at skabe din personlige akustiske profil. Ved at integrere det i TONALITE-systemet er øretelefonerne færdiggjort til at levere en personlig, naturlig klangfarve, der er unikt skræddersyet til dig.

Fordi hver brugers kropsform er unik, er de lydegenskaber, der udledes af DTAS, også unikke. Derfor kan ingen konventionel tuning af øretelefonens lyd udføres. Med andre ord eliminerer DTAS behovet for standard produkttuning, da øretelefonerne er optimeret individuelt til hver lytter.

DTAS' lyd

Trofast klangfarvegengivelse har været svær – eller endda umulig – med konventionelle øretelefon-designmetoder, som bruger en enkelt målresponskurve for alle brugere. Som følge heraf er klangfarven ofte blevet beskrevet af øretelefonproducenterne ved hjælp af en bred vifte af tonale impressionsudtryk, og indtryk kan variere meget mellem lyttere.

Når man lytter til levende akustiske instrumenter, evaluerer de fleste ikke fremførelsen i form af klanglige indtryk eller lydspecifikke deskriptorer. I stedet fokuserer de intenst på selve musikken.

I modsætning hertil, for konventionelle øretelefoner, begynder lyttere ofte instinktivt at evaluere klangfarve og lydkvalitet med det samme i stedet for at engagere sig i musikken . Dette sker, fordi klangfarven ikke gengives præcist eller naturligt – artefakter eller unaturlige komponenter i lyden tiltrækker opmærksomhed og forhindrer fuldt engagement med musikken.

Fordi de lydegenskaber, der udledes af DTAS, er unikke for hver brugers kropsform, fjerner det disse klanglige problemer og artefakter. Som følge heraf er der, når man lytter gennem TONALITE, intet behov for at kritisere lydkvalitet eller tonale karakteristika. Lyttere kan fokusere helt på musikken og opleve et niveau af naturlig, trofast klangfarvegengivelse, der tidligere var umuligt. Dette muliggør en helt ny måde at nyde musik på – fordybet udelukkende i fremførelsen, uden distraktioner fra bekymringer om lydkvalitet.

Lyden af DTAS er blevet subjektivt evalueret af trænede lyttere og opnåede højere score i klangfarveopfattelse sammenlignet med Diffuse Field Target Curve og Listener Preferred Target Curve, som almindeligvis bruges i øretelefon-design.

Lyden af TONALITE

TONALITE tilbyder 2 typer DTAS-lydprofiler :

DTAS General (Instant Enjoyment): Lige ud af æsken kan du nyde vores generaliserede standardlydprofil. Dette er ikke bare en \

DTAS Personalized (Your Ultimate Sound): This is the full TONALITE experience. By completing a series of scans with the dedicated app, you generate a sound profile that is 100% unique to your individual anatomy. This profile unlocks the most natural and faithful timbre possible, tailored perfectly for you.

DTAS Process with Mobile App

The scanning required for DTAS Personalized is performed using the dedicated TONALITE app on the user’s smartphone. The captured data is then sent to our cloud servers, where calculations and simulations are performed to generate the personalized timbre profile.

The app supports 3 languages: English, Simplified Chinese, and Japanese, and is compatible with iOS 17 or later on iPhone and Android 14 or later on Android devices.

The DTAS Personalized profile is stored directly inside TONALITE. Once the setup process is complete and the sound mode is switched to DTAS Personalized in the app, TONALITE will retain that setting. You can then disconnect from your current device, pair TONALITE with any other Bluetooth device, and continue enjoying your Personalized Timbre seamlessly.

As the DTAS process involving sending scan and measurement data to the cloud server for simulation and calculation, and also downloading result into the TONALITE, a stable internet connection is needed during the process.

World leading Hardware

Ultra-Low THD Transducer

To accurately deliver the personalized sound of the DTAS, the match between the calculated DTAS result and the earphone’s acoustic output is controlled to within 0.1 dB. Such precision is impossible with conventional earphone drivers due to their high total harmonic distortion (THD).

The driver in an earphone plays a critical role in delivering sound that is both accurate and faithful to the electronic audio signal. To evaluate a driver’s fidelity, THD is commonly measured by comparing the difference between the input and output signals; lower THD indicates more accurate sound reproduction .

final has a long history of designing and manufacturing our own dynamic drivers, with a strong focus on minimizing THD and optimizing impulse response. We explore a wide range of materials and cutting-edge manufacturing techniques to achieve these objectives.

f-CORE for DTAS

In 2022, by employing a true CVD diamond dome and our proprietary fabrication technology, we successfully created our first diamond-dome dynamic driver prototype. The results were astonishing—the THD of the driver was nearly zero across the entire audible range. This was an industry breakthrough, as achieving near-zero THD in the low-frequency range had never been accomplished before. With this new prototype driver, we discovered new possibilities in earphone sound. The driver has since been successfully mass-produced in-house and is currently used in final’s latest flagship $2,999 IEM, the A10000.

Inspired by the performance and advantages of this near-zero-THD design, we developed f-CORE for DTAS: a new 10 mm dynamic driver with ultra-low THD characteristics specifically optimized for DTAS and wireless TWS applications. We are proud to say that f-CORE for DTAS is the driver with the lowest THD among all TWS solutions available today.

Its THD is so low that it exceeds the measurement capability of typical systems used on TWS production lines. Therefore, every f-CORE for DTAS driver is measured using a high-precision R&D-grade Audio Precision system during production, ensuring that all drivers used in assembly fully meet the strict DTAS requirements.

Electronic Components

We envision implementing DTAS as a new standard in portable audio. To achieve this, it was essential to develop TONALITE as a true wireless stereo (TWS) earphone, enabling this technology to reach a broad audience.

However, no matter how good the sound, a daily-use TWS device must also include features such as active noise cancellation (ANC), ambient mode, and other essential functions to be widely accepted in the market. Therefore, a core development goal was to make TONALITE’s basic performance among the world’s best in the TWS category.

Each side of TONALITE is equipped with three of the highest-spec MEMS microphones available (Infineon IM73A135), SONY Semiconductor flagship ANC IC (CXD3784), and final Fusion-G hybrid ear tips made of foam and silicone, renowned for superior passive noise isolation, combined with our proprietary in-house ANC algorithms.

With this combination, TONALITE achieves high quality ANC and ambient mode performance, supported by the finest components currently available.
