People Hear TDT and Think Auditory Neuroscience

Tucker-Davis Technologies has been pioneering auditory neuroscience research tools and software since 1988. We provide solutions for pre-clinical drug testing to mitigate or reverse hearing loss, basic auditory science, and research in psychoacoustics and operant behavior.

Our ABR and DPOAE systems have been, and remain, the industry gold-standard. Recently, we have expanded our auditory system offerings with our new low-cost iCon platform.

Build your custom recording system from over 28 modules designed for high-ultrasonic stimulation, electrophysiology, operant paradigms, fiber photometry, and much more. TDT is unmatched in its engineering legacy, innovation, and commitment to its customers.

 

The Most Cited ABR & DPOAE System In History

ABRs & DPOAEs

When it comes to Auditory Brainstem Responses (ABRs) and Distortion Product Otoacoustic Emissions (DPOAEs), TDT is well-regarded as the system to purchase.

The RZ6 Multi-I/O Processor is TDT’s turnkey solution for ABRs and DPOAEs. This embedded system provides real-time control of simple or complex waveforms, output normalization across all frequencies, and immediate signal viewing and analysis.

Combined with our flagship auditory software BioSigRZ, users have a complete system for rapid phenotyping, drug screening, pre-clinical hearing trials, and more.

Simple Programming with Precision Results

PsychoAcoustics

TDT is the only system that can combine acoustic stimulation control with real-time EEG and external button response collection.

Everything is synchronized and controlled in one place and controlled with our Pynapse state-machine software.

Easily create innovative subject response paradigms while collecting high-fidelity analog ephys signals.

Pups, Predators, and Potentials

Behavioral Neuroscience

Ultrasonic animal calls, startle responses, tuning curves, auditory evoked responses and more!

The TDT iCon and iQ Auditory Stimulation Module make running any acoustic paradigm a breeze.

Combine your iQ2 or iQ4 with electrophysiology or fiber photometry plus video to get a complete picture of neural activity and social behavior.

 

Why TDT?

When you choose a TDT behavioral neuroscience recording system you choose legacy, innovation, and commitment. Every system is designed and assembled at our headquarters in Alachua, Florida by our long-time employees.

Legacy

Tucker-Davis Technologies has been pioneering auditory neuroscience research tools and software since 1988. Our systems are widely used across the globe for every type of auditory application and includes pre-clinical drug testing to mitigate or reverse hearing loss, basic auditory science [DOI: 10.1016/j.celrep.2019.10.049], and research in psychoacoustics and operant behavior. Our ABR and DPOAE systems have been [DOI: 10.1097/00129492-200301000-00012], [doi.org/10.1016/j.heares.2008.09.001], and remain, the industry gold-standard, and are still being used to test the leading front of novel hearing therapies [https://www.cell.com/med/abstract/S2666-6340(26)00004-8].

Innovation

While our RZ6 system is still a flagship processor for many labs and auditory applications, we realized that a more complete integration of auditory stimulation with other neuroscience recording techniques, such as fiber photometry, video recording, high channel count electrophysiology, and operant behavior,was necessary to exceed the expectations of our customers and to deliver the best product possible. This lead us to developing the low-cost iCon platform and the iQn and iMn auditory stimulation modules. The iQ2 and iQ4 are our finest stimulus generators ever developed and allow customers to play out sounds with a sampling rate up to 400 kHz, doubling the former capabilities of the RZ6. The iMn family of modules are perfect for most behavioral paradigms involving pure tones and gaussian noise.
