- Observational Model: None
- Primary Purpose: OTHER
- Time Perspective: None
- Masking: DOUBLE
- Phase: PHASE2

Eligibility Criteria:
Key Inclusion/Exclusion Criteria~Inclusion Criteria Group A:~1. Healthy adults, 18-50 years old~2. Subject is able and willing to comply with the protocol and attend all study visits~3. Subject is able and willing to provide informed consent~4. Subjects with air conduction hearing thresholds of 25 dB HL or better at standard frequencies up to 2000 Hz, and 45 dB or better at 4000 Hz.~5. Subject is able to read and understand English~Exclusion Criteria Group A:~1. Pregnant or lactating females.~2. Prior ear iontophoresis procedure~3. Subjects with conductive hearing loss.~4. Subjects with history of sensitivity or allergic reaction to lidocaine HCl, tetracaine, epinephrine, or any hypersensitivity to local anesthetics of the amide type, or any component of the anesthetic drug formulation.~5. Familial history of insensitivity to lidocaine or other local anesthetics of the amide type.~6. Significantly atrophic, retracted, bimeric, monomeric or atelectatic tympanic membrane.~7. Perforated tympanic membrane.~8. Subjects with known history of ear surgery or TM condition that has the potential to affect the sensitivity of the TM~9. Otitis externa.~10. Damaged/denuded skin in the auditory canal.~11. Subjects with electrically sensitive support systems~12. Cerumen impaction resulting in a significant amount of cleaning required to visualize the tympanic membrane.~13. Evidence of Otitis Media at day of procedure, or within the past three (3) months prior to procedure.~14. Other conditions that would preclude performing the study procedure including ear plug incompatibility.~15. Health conditions that, in the opinion of the investigator, would present undue risk to the subject, based on device/anesthetic drug product label warnings and precautions.

Study Arms:
- Active Tymbion Iontophoresis (Type: EXPERIMENTAL): Unilateral treatment with active iontophoresis of Tymbion (2% lidocaine HCl/ 1:100,000 epinephrine) using the Tusker Medical Tula Iontophoresis System.
- Sham Tymbion Iontophoresis (Type: SHAM_COMPARATOR): The sham iontophoresis procedure will be identical to the active Tymbion iontophoresis in that Tymbion (2% lidocaine/ 1:100,000 epinephrine solution) will be placed in the external ear canal, however the iontophoresis current delivery (which facilitates penetration of drug into the tympanic membrane tissue) will not be activated.

Based on this trial design, predict the completion outcome and termination type (if applicable).
