Summary
This study established normative nasalance scores for Turkish-speaking children and adults using the Nasometer. The findings provide a crucial reference for evaluating speech nasality in this population.
Area of Science:
- Speech-Language Pathology
- Acoustic Analysis
- Linguistics
Background:
- Nasalance measurement is essential for assessing speech disorders.
- Normative data is lacking for Turkish-speaking populations.
- Establishing reference values aids in accurate clinical diagnosis.
Purpose of the Study:
- To obtain normative nasalance scores for Turkish-speaking children and adults.
- To establish a reference range for normal nasality.
- To aid in the evaluation of speech nasality.
Main Methods:
- 35 children (7-13 years) and 125 adults (18-69 years) participated.
- Participants repeated three passages: oral, oronasal, and nasal.
- Nasalance scores were collected using the Nasometer (model 6400).
Main Results:
- Mean nasalance scores varied significantly between oral and nasal passages for both age groups.
- Children's scores (oral, oronasal, nasal): 15.14±4.81, 37.76±4.42, 49.23±6.95.
- Adults' scores (oral, oronasal, nasal): 13.46±6.26, 37.84±6.13, 50.28±7.77.
Conclusions:
- Normative nasalance values for Turkish speakers were successfully obtained.
- The study confirmed significant differences between oral and nasal speech sounds.
- These normative scores serve as a valuable clinical reference for Turkish speech evaluation.

01:29Introduction to Normal Distributions
Standardized test scores often follow a symmetric distribution that can be modeled with the normal distribution, a fundamental concept in statistics. This distribution is particularly useful for interpreting test performance fairly across populations, as it provides a mathematical framework for understanding variability and central tendency in large datasets.From Histogram to Frequency DistributionRaw test data are often displayed using histograms, where the height of each bar represents the...
01:20Sign Test for Median of Single Population
In general, the sign test serves as a nonparametric method to test hypotheses about the median of a single population when the data does not follow a known distribution. This simplicity makes it particularly useful for small sample sizes or when the assumptions of parametric tests cannot be met. The process begins with identifying a null hypothesis, typically stating that the population median equals a specific value. The alternative hypothesis could be that the median is either not equal to,...
01:07z Scores and Unusual Values
The z score is one of the three measures of relative standing. It describes the location of a value in a dataset relative to the mean. z scores are obtained after the standardization of the values in a dataset. The z score for the mean is 0.
This score indicates how far a value is from the mean in terms of standard deviation. For example, if a data value has a z score of +1, the researcher can infer that the particular data value is one standard deviation above the mean. If another data value...
