What is Soundscape Ecology?

It is the study of ecosystems through their sound. Unlike traditional ecology, which relies heavily on visual observation and quantitative metrics, soundscape ecology embraces the auditory dimension of life. It captures and analyzes the complex sonic environments of habitats using three key categories defined by Krause:

• Geophony: Non-biological natural sounds. Think rain, wind, earthquakes, or a river's flow. These form the timeless background of a place.
• Biophony: All the vocalizations of non-human animals, from insects and amphibians to mammals and birds. Together, they form nature’s choir.
• Anthrophony: The sounds created by human activity. This can range from footsteps on a trail to the invasive roar of airplanes.

By recording, analyzing, and comparing these layers, scientists can detect biodiversity shifts, habitat fragmentation, climate change impacts, and even anticipate ecological collapse. Acoustic data is incredibly efficient: a few days of recording can yield more biodiversity insights than weeks of visual surveys.

Krause's discovery that healthy habitats exhibit rich, structured acoustic niches, while degraded environments go silent or chaotic, has revolutionized conservation. Soundscapes have become a new lens to measure the pulse of the planet.

Climate Change has a Sound

Climate change is not just visible in melting glaciers or rising seas. It is audible in the quieting of rainforests, the dissonance of coral reefs, or the delayed migration songs of birds. The Earth is losing its rhythm.

Krause and other researchers have shown how acoustic degradation is one of the earliest indicators of ecological stress. Animals alter their vocal behavior due to:

• Shifts in temperature and precipitation
• Loss of habitat and food sources
• Ocean acidification and underwater noise pollution
• Human-induced landscape fragmentation

The changes are subtle but measurable. Choruses become fragmented. Frequencies clash. Biodiversity declines. Silence creeps in.

However, there is hope. Acoustic monitoring has also proven effective in documenting ecological recovery. Rewilded areas show increasing biophonic complexity over time, offering data-backed evidence for restoration efforts.

Costaphonics applies these methods in Costa Rica, one of the world’s most biodiverse nations, tracking the soundscape of its ecosystems to monitor regeneration and document climate impact.

Well-being & Sound

Natural soundscapes don’t just help ecosystems—they heal us, too.

An increasing body of research from institutions like Stanford, Carleton University, the NIH, and published in journals like PNAS and Frontiers in Psychology, proves that listening to natural sounds reduces stress, anxiety, and fatigue. It enhances mood, memory, and focus.

Health Benefits of Natural Sound Exposure:

• Reduces cortisol (stress hormone)
• Lowers heart rate and blood pressure
• Increases parasympathetic nervous system activity (rest/digest response)
• Improves quality of sleep
• Enhances attention and emotional regulation
• Aids recovery in hospital environments

This is the foundation of Soundscape Therapy, an emerging practice that incorporates:

• Deep Listening: A meditative practice developed by Pauline Oliveros that fosters mindful sonic awareness.
• Vibroacoustic Therapy: Uses sound frequencies delivered through the body via vibrating surfaces.
• Binaural Beats and Biophonic Soundtracks: Calibrated to stimulate specific brainwave states (alpha, theta, delta).

We use these tools in our Enhanced Listening Experiences to help individuals reconnect with nature while improving their emotional and physical health.
