Which intervention is suitable for a patient with presbylaryngis who has vocal loudness issues?

For a patient with presbylaryngis experiencing vocal loudness issues, producing phrases with high vocal intensity is an effective intervention. This condition typically involves physiological changes in the larynx due to aging, resulting in a reduction of vocal loudness and clarity. By focusing on increased vocal intensity in a structured way, the patient can work on improving their vocal projection and strength.

In many cases, encouraging the use of high vocal intensity can help stimulate the vocal folds and improve overall vocal quality. This method also provides the opportunity for the patient to practice effective breath support and resonance, which can further enhance vocal loudness.

The other options may not effectively address the vocal loudness issues associated with presbylaryngis. Voice rest or complete silence can lead to muscle atrophy or increased vocal fold tension rather than strengthen the voice, making them less suitable in this context. Meanwhile, sigh phonation typically emphasizes relaxation and ease of phonation rather than the specific goal of increasing vocal intensity, which is crucial for patients dealing with loudness problems.
