PMID 35352792WHAT IT FOUND
Chilean adults without speech issues produced specific nasalance scores across oral, nasal, and oronasal passages.
These baseline numbers provide a reference for identifying abnormal nasal resonance in this population.
Key findings
01Mean nasalance scores were highest for the nasal passage, intermediate for the oronasal passage, and lowest for the oral passage.
02No statistically significant differences were found in nasalance scores between men and women.

What it does not show
The study only included adults aged 18 to 35, so these values do not apply to children or older adults. Participants were recruited from a single institution in Santiago, which may not represent all regional dialects or populations in Chile. The Nasometer model used (6450) can yield different results compared to older models (e.g., 6200), limiting direct comparison with some previous studies.

The easy way to misread this
Do not apply these normative values to patients outside the 18-35 age range or to speakers of other Spanish dialects, as nasalance scores vary by age, language, and regional accent.
