Now updated - "Low Frequency Detector" ver 4.0

icon-lfd_v400.png

"Low Frequency Detector"has been updated to ver 4.0 today!

"Low Frequency Detector" is a new acoustic measurement tool for detecting low frequency sounds that is hard to hear in the normal situation. It supports very lower frequency range less than 100Hz by our proprietary sound sensing technology.

This app also allows you to examine the frequency component of the low frequency sounds by 1/3 octave band analysis and FFT analysis.

The human ear is insensitive enough to become a low frequency. If you may be exposed to the noise of neighboring constructions and factories without noticing, you may have a feeling bad and a sense of oppression. In this case, you can check what type of the low frequency noise exists by simple operation of this app.

In the latest version, we have reduced the tuning process by improving the calibration process. This makes the initial setup a very simple procedure.

The following are some of the sources of infrasound. If you have unexplained health problems or feel unwell, you may be exposed to such low frequency sounds.

# Sources in the home: heat pump water heaters, household fuel cells, ventilation fans, refrigerators, air conditioners, blowers, dehydration pumps, etc.

# Outdoor sources: cars, trains, airplanes, outdoor air conditioning units in buildings, factory noise, long-term vibration of road bridges, wind power generation, etc.

Detailed information about this app is available on the AppStore and can be found at the following link.

Lighting up Nijojo Castle

nijyo-2021-11-2.jpg

In autumn in Kyoto, the sun sets very early. As I happened to be walking along Horikawa Dori, I came across a very bright yellow light. It was the illuminated Nijojo Castle.

nijyo-2021-11-1.jpg

As I walked closer, I saw that a nighttime event called "Nijojo yakai" was taking place.

It was an immersive, participatory digital art event using AI-driven large-scale projection mapping.

Awata-matsuri festival

awata-2021-4.jpg

The Awata-matsuri festival was held last weekend at Awata shrine in Kyoto, a festival with a history of over 1,000 years.

awata-2021-5.jpg

Last year, this festival had been cancelled due to COVID-19. Knowing that this festival would be resumed this year on a smaller scale, I went to see it. Since it is not a famous festival, there were not many spectators outside the neighborhood, so I felt very safe.

awata-2021-0.jpg

Last Saturday evening, "Yowatari" ritual procession was held to purify the route of the portable shrine for the next day, and the floats were paraded through the town with large lanterns lit.

awata-2021-3.jpg

These large lanterns were revived in 2008 for the first time in 180 years.

awata-2021-1.jpg

The students of Kyoto University of the Arts created the lanterns of Isotakeru no Mikoto and next year's zodiac sign, the tiger, in 1/2 scale. There were three of them, including the one made last year.
It was impressive to see the students involved in the making of the lanterns earnestly pulling the large lanterns.

Hopefully next year we can overcome COVID-19 and the festival can be held on its original scale.

Fujibakama and butterfly

tsumagurohyomon-202110.JPG

I was walking along Teramachi street in Kyoto when I came across an exhibition of Fujibakama (Eupatorium japonicum) at Kodo Gyoganji Temple.

This Fujibakama is an ancient species that originated in Kyoto over 1200 years ago.

Among the many Fujibakama flowers on display, I found a beautiful butterfly in a large pot!

tsumagurohyomon-202110-2.JPG

This butterfly appeared to be a female Indian Fritillary. The leopard print wings were very eye-catching.

She was engrossed in sucking the nectar from the flowers, even though I was watching her very closely.

It is said that this type of butterfly ingests pyrrolizidine alkaloids, a chemical found in the nectar of Fujibakama flowers, and stores it in its body to protect itself from enemies and as a source of sex pheromones. She may have been intoxicated by this ingredient.

I was very healed by this beautiful butterfly.

"Jugatsuzakura" in Kyoto Gyoen.

gosho-jyugatusakura-2021-1.JPG

The declaration of a state of emergency throughout Japan has been lifted on October 1, and I hope that the COVID-19 pandemic will gradually come under control.

I went for a walk in the Kyoto Gyoen Imperial Garden on a sunny day. It's been half a year since I came here to see the cherry blossoms in early spring.

On the east side of "Demizu no Ogawa" creek, pink flowers were blooming! Just like the scene I saw this spring.

gosho-jyugatusakura-2021-2.JPG

The flowers are called "Jugatsuzakura," a type of cherry blossom that blooms in two seasons, early April and October through winter.

I was able to see it bloom at just the right time. I think it is a new tree that was planted five or six years ago, but I didn't know that it also blooms in autumn.

gosho-jyugatusakura-2021-3.JPG

This pretty pink flower has healed my heart. It is still in its early stages of blooming, so we will be able to enjoy these pretty flowers for a while.

New release app - "High-Frequency Noise Monitor"

icon-hfnm_v100.png

"High-Frequency Noise Monitor" has been newly released now!

"High-Frequency Noise Monitor" is a high-frequency noise analysis tool that specializes in high-frequency bands above 8 kHz.

You may be exposed to artificial high-frequency noise on a daily basis that is inaudible to the human ear. This app allows you to monitor such high frequency noises and examine their occurrence.

In general, noise may contain relatively high frequency components depending on its source, and this is classified as high frequency noise.

For example, harmonic noise is radiated from the main body of an electronic device or the power lines of a power conversion device such as an AC-DC power adapter, and depending on its power level, it may affect peripheral devices.

There are also devices that generate high-frequency noise to drive away vermin such as rats and weasels. The frequency of the sound varies depending on the type of vermin, and some devices incorporate sensors to change the volume and frequency over time. When such devices are installed in the vicinity, there are cases where they can lead to noise problems with adverse effects on human health.

High-frequency noise does not often occur at a constant volume or frequency, but often occurs in a certain cycle or randomly. It is not easy to detect such high-frequency noise.

This app records randomly fluctuating high-frequency noise from the iPhone built-in microphone and performs frequency analysis in real time.

hfnm_main_1a_v100.png

In addition, it retains the PCM data for 20 seconds just before the measurement is stopped, and displays a spectrogram by FFT or the octave band analysis.

The spectrogram is a graph showing the analysis results of the frequency spectrum of sound with time on the vertical axis, frequency on the horizontal axis, and signal strength in colors, allowing visual observation of the occurrence of high-frequency noise.

* Spectrogram by FFT
hfnm_fft_1a_v100.png

* Spectrogram by Octave band analysis.
hfnm_oct_1a_v100.png

We have also released iPhone app, "Mosquitone Detector" which detects high frequency noise and ultrasound. This app has the ability to detect the presence of high frequency noise and search for the direction of the sound source.
We hope our these apps will be useful for dealing with high-frequency noise problems.
