Our nature sound album "Nature Sound Symphony - Natural sounds from national parks that lead to relaxation" was used in the September 14th broadcast of " Weather Newscaster " (TBS Television, every Saturday from 23:25, Kanto local), a program that introduces weather information, food that you'll want to eat and fashion that you'll want to wear tomorrow, with the concept of "Just a little bit more!"

The program focused on " 1/f fluctuations " as the reason why sounds of nature, such as the sounds of autumn insects and the murmuring of a river, have a soothing effect on us, and introduced national parks, in particular, where diverse nature thrives, as healing places that bring peace to our hearts.
We also mentioned our nature sound streaming service as a way for people who find it difficult to visit national parks in person to enjoy the rich sounds of nature from the comfort of their own homes.

Our "Nature Sound Symphony - Relaxing Natural Sounds from National Parks" contains natural sounds from Japan's beautiful national parks. The recorded natural sounds contain this "1/f fluctuation," which calms the listener's mind and leads them to relaxation.

This album was produced as part of the " National Parks Official Partnership " initiative promoted by the Ministry of the Environment, and features re-edited audio from works that Della has previously released on CD or digitally, as well as natural sounds from 12 national parks across the country.
The sound covers Japan's easternmost national park, Shiretoko National Park, to its westernmost, Iriomote-Ishigaki National Park, allowing you to hear the diversity of the area.


"1/f fluctuation"
(Reading: Efubunnoichiyuragi)
It refers to the "fluctuations (=irregularities)" that arise in part in reaction to the regularity of sound, light, air flow, and the movement of objects, and refers to unpredictable changes and movements that exist in the natural world.
Irregular fluctuations such as natural sounds like a babbling brook or the sound of rain, as well as candle flames, twinkling stars, sunlight filtering through the trees, birdsong, and the swaying of a train are also said to be 1/f fluctuations.
