NCT01009632

Brief Summary

The purpose of this study is to explore quantitatively the hypothesis that "resonant voice," may enhance recovery from acute laryngeal phonotrauma, based on molecular assays from human laryngeal secretions and secondarily, clinical tests.

Eligibility Criteria

Age18 Years - 49 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • males and females who have had voice training and feel they are able to produce loud voice safely;
  • ages 18-49;
  • generally healthy;
  • normal hearing bilaterally at 20 dB to 8,000 Hz; and
  • demonstrated ability to produce "resonant voice" during training as determined by the examiner perceptually.

You may not qualify if:

  • current chronic voice problems;
  • current medications that are determined to possibly influence voice (e.g. diuretics, decongestants);
  • heightened gag reflex;
  • small nasal passage;
  • deviated septum; and
  • known or suspected allergy to anesthetics.
