Our journey
It began with a father, a son, and a shared belief.
GrandAudition USA was born from a shared mission between father and son. For over 20 years, Daniel and Jonathan Abittan have dedicated their careers to one thing: helping people across South Florida reconnect to the sounds, voices, and moments that matter most. What began as two trusted practices, HearingSpace and Advanced Audiology, has grown into a single, family-led brand built on craftsmanship, compassion, and a refusal to settle for ordinary hearing care.
01.
A Highly Respected Clinical Protocol
Most hearing care visits follow a familiar pattern: a test, a recommendation, a fitting.
GrandAudition works differently. Every patient - regardless of the complexity of their case or the device they choose - follows a defined five-step clinical protocol that ensures nothing is rushed and nothing is missed.
02.
100+ Criteria Guide Every Recommendation
The hearing aid recommendation a patient receives at GrandAudition is not based on what is in stock, or what one practitioner happens to prefer. It is guided by a proprietary selection framework that integrates more than 100 objective criteria to identify the most appropriate solution for each individual.
Device selection is further informed by GrandAudition’s independent bench-testing programme - a rigorous scientific evaluation of hearing aids from every major manufacturer, designed to cut through marketing claims and identify what genuinely performs. The device recommended is the right device.
03.
Personalized. Not Off the Shelf.
Solutions are selected and configured to the precise requirements of each patient’s individual hearing profile - factoring in listening environments, lifestyle, and the specific ways their hearing loss presents.
The result is a hearing solution that performs more consistently and feels more natural — because it was chosen and calibrated for you specifically, not approximated for the average patient.
04.
Calibrated to 120 Frequency Points
Most fittings are approximations. GrandAudition fittings are not. Our proprietary High-Definition Objective Measurement technique tests the hearing correction delivered across 120 individual frequency points - identifying and eliminating any peaks or gaps in the response curve that a standard fitting would leave in place.
Each adjustment channel is refined to the exact decibel. The result is not just amplification. It is precision calibration - closer to the experience of natural hearing than any standard fitting process can reliably achieve.
05.
Fast Turnaround. Minimal Disruption.
Many adjustments and fittings are completed within a single appointment for stocked, non-custom devices - without reliance on external manufacturers or waiting on return windows.
For repairs and custom work, our team advises on realistic timelines upfront. Patients are never left uncertain about where things stand
06.
A Brain-First Approach to Adaptation
Fitting a hearing device is the beginning, not the end. When hearing loss develops gradually over time, the brain’s auditory cortex becomes less efficient at processing sound - and fitting a device alone does not restore that.
GrandAudition integrates tools to accelerate adaptation, retraining the auditory system’s ability to locate sound in space and separate speech from background noise - the two skills most critical to hearing clearly in real-world environments.
07.
Specialist Care for Tinnitus and Sound Sensitivity
GrandAudition supports patients managing tinnitus and sound sensitivity with targeted clinical approaches designed to reduce long-term impact on daily life - not just temporary relief.
08.
An Experience Built Around the Patient
Appointments are not rushed, conversations are not cut short, and every interaction is designed to feel unhurried, considered, and genuinely focused on the individual.
Patients leave with a clear understanding of what is happening with their hearing, why a specific solution has been recommended, and what the next step in their care will be.
09.
20 Years of Clinical Excellence
GrandAudition’s approach reflects two decades of clinical refinement, patient trust, and continuous investment in both technology and people. Our practitioners attend major international ENT and audiology congresses - ensuring clinical practice is informed by the latest research.
10.
Continued Follow-Up, Included as Standard
The fitting appointment is not the end of the relationship. Every hearing device purchased at GrandAudition is followed by included aftercare - adjustments, fine-tuning, maintenance, and reassessment - all part of the same clinical commitment.
11.
No Waiting. No Compromise.
GrandAudition does not operate waiting lists, rushed appointments, or constrained clinical time. Each patient is seen when they need to be seen, for as long as the appointment requires, with access to the full clinical team from day one.
That is not a premium add-on. It is simply what hearing care looks like when it is done properly.
Our values
At GrandAudition USA, our work is guided by the values we've built our family practice on. Compassion for every patient. Craftsmanship in every fitting. And an unwavering commitment to personal, premium care. These values shape every conversation we have, every decision we make, and every relationship we form.
Our approach
We believe great hearing care starts with truly listening. To your story, your goals, and the moments you want to hear more clearly. From your first conversation to a lifetime of follow-up visits, we work alongside you to make sure your hearing supports the life you want to live, not the other way around.
