Instrumentation Amplifier

Instrumentation Amplifier

An electrocardiography (ECG) machine is an essential piece of medical equipment used to monitor the electrical activity of the heart. It operates by detecting small electrical changes on the skin that result from the depolarization of the heart muscle during each heartbeat. However, these signals are in the microvolt range and can be easily overwhelmed by noise or interference.
To overcome this challenge, an ECG machine utilizes an instrumentation amplifier. This specialized amplifier is...

Electronic Distance Measuring Instruments

Electronic Distance Measuring Instruments

Electronic Distance Measuring Instruments (EDMs) are essential tools in modern surveying, offering precise distance measurements by emitting electromagnetic signals and calculating the time required for these signals to travel to a target and return. Two primary types of signals are used in EDMs — light waves and microwaves — each suited to specific environmental and distance requirements. Light-wave-based EDMs utilize either infrared or laser light, providing high accuracy over short distances...

Area of Science:

Speech-Language Pathology
Linguistics
Developmental Psychology

Background:

Accurate assessment of speech production is crucial for diagnosing speech sound disorders (SSDs).
Existing assessment tools may not adequately address the specific needs of Brazilian Portuguese-speaking populations.
Digital platforms offer potential for standardized and accessible speech evaluations.

Purpose of the Study:

To develop and validate a Digital Speech Assessment Instrument for Brazilian Portuguese-speaking children and adolescents.
To evaluate phonological and motor speech skills, including word and pseudoword processing and diadochokinesis.
To create an online tool for efficient and accurate speech assessment.

Main Methods:

A seven-step development and validation process was employed.
The instrument includes tasks for word naming, imitation, repetition, pseudoword imitation, pseudoword repetition, and diadochokinesis.
Pilot studies were conducted with children and adolescents with typical speech development and SSDs.

Main Results:

The Digital Speech Assessment Instrument comprises 91 real words, 26 pseudowords, and 6 diadochokinesis stimuli.
Stimuli include images, audio, and video recordings, with data stored in a virtual database.
The instrument is designed for individuals aged 2;0 to 17;11 and is administered online.

Conclusions:

The Digital Speech Assessment Instrument has been successfully developed and validated for Brazilian Portuguese.
This online tool evaluates various aspects of speech production in children and adolescents.
The instrument holds potential for timely and accurate diagnosis of speech sound disorders.
