What Birds Hear – Understanding Avian Hearing and Behavior
By Janet Marlow, M.A., Sound Behaviorist & Founder of Pet Acoustics

Birds experience the world through sound in ways most people never realize.
What Birds Hear reveals how avian hearing shapes behavior, communication, stress responses, and overall well-being—and how small changes in a bird’s sound environment can make a powerful difference.

Written by internationally recognized sound behaviorist and Pet Acoustics founder Janet Marlow, this book translates science into practical, compassionate guidance for bird caregivers and professionals alike.

Inside, you’ll discover:

• How birds hear differently from humans—and why it matters

• The link between sound, behavior, and emotional health in birds

• How everyday household and environmental sounds can affect stress and comfort

• Simple ways to create a calmer, more supportive sound environment

• How sound awareness can improve handling, enrichment, and quality of life

Whether you share your life with a companion parrot, work in avian veterinary care, rehabilitation, or rescue, What Birds Hear offers a new perspective on listening to birds—by understanding how they truly hear.

This book is part of Janet Marlow’s What Animals Hear series, supporting Pet Acoustics’ mission to advance hearing health and sound-based emotional care for animals worldwide.

A must-read for bird lovers, veterinarians, technicians, rehabilitators, and anyone who wants to create a calmer, healthier world for birds.
