The Effect of Aging on Tissues01:19

The Effect of Aging on Tissues

Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...
Perception of Sound Waves01:01

Perception of Sound Waves

The human ear is not equally sensitive to all frequencies in the audible range. It may perceive sound waves with the same pressure but different frequencies as having different loudness. Moreover, the perception of sound waves depends on the health of an individual's ears, which decays with age. The health of one's ears may also be affected by regular exposure to loud noises.
The pitch of a sound depends on the frequency and the pressure amplitude of the source. Two sounds of the same frequency...
Larynx01:21

Larynx

The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...
Bone Disorders01:29

Bone Disorders

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
Aging01:26

Aging

Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...
Alzheimer Disease l: Introduction01:29

Alzheimer Disease l: Introduction

Alzheimer disease is a chronic, progressive, and irreversible neurodegenerative disorder and the most common cause of dementia in older adults. It leads to gradual neuronal loss, causing cognitive decline, behavioral changes, and loss of functional independence.Risk Factors and EtiologyThe disease is multifactorial. Age is the strongest risk factor, with prevalence doubling every 5 years after age 65. Genetic factors include mutations in genes such as APP, PSEN1, and PSEN2, which are associated...

Summary

Speaking fundamental frequency (SFF) changes with age differ between sexes. While males show minimal SFF changes, females experience a notable decrease, particularly in middle age, with implications for laryngeal health detection.

Area of Science:

  • Laryngology
  • Acoustic analysis
  • Human aging studies

Background:

  • Speaking fundamental frequency (SFF) is a key acoustic measure of voice.
  • Aging can influence vocal characteristics, but sex-specific changes in SFF require detailed investigation.

Purpose of the Study:

  • To investigate age-related changes in speaking fundamental frequency (SFF) in healthy males and females.
  • To establish normative SFF data across different age groups for clinical application.

Main Methods:

  • Acoustic analysis of SFF was performed on 374 healthy participants (187 males, 187 females) across adolescent to older age ranges.
  • Participants read a standardized passage aloud to capture vocalizations.

Main Results:

  • Males showed no significant SFF trend with age, except a slight increase in those 70+ years.
  • Females exhibited lower SFF in their 30s-40s compared to their 20s, with a marked decrease across all ages.
  • The magnitude of SFF change with aging was significantly greater in females than in males.

Conclusions:

  • Aging impacts male and female SFF differently, with females experiencing more pronounced vocal changes.
  • Established reference intervals for SFF can aid in the clinical detection of vocal abnormalities and laryngeal diseases.
