"Nagoshi no Harai" at Yasaka Shrine in Kyoto


I went to Yasaka Shrine today because I can't go to the "Nagoshi no Harai" ceremony tomorrow.

The number of visitors has increased slightly from last month. Before COVID-19, there were so many tourists that it was hard to walk past them.

Now I feel that Yasaka Shrine has returned to the quiet atmosphere of the past.


A big ring of grass, "Chinowa" has been set up beside the main shrine building at Yasaka Shrine.

It has been set up since March this year for praying for the end of the new coronavirus pandemic. Usually, it is only made and installed for a few days for ceremonial purposes.


I walked through the ring and prayed for good health and protection from the new coronavirus.

New updated - "Low Frequency Detector" ver 3.0


"Low Frequency Detector" was updated to ver 3.0.

"Low Frequency Detector" is a new acoustic measurement tool for detecting low frequency sound/noise that is hard to hear in the normal situation.

This app can display the frequency component of the low frequency sound by examining by 1/3 octave band analysis and FFT analysis.

In the latest version, it has updated UI design and improved stability.


Low frequency sound is lurking everywhere in everyday life.

Unlike general noise, low frequency sounds are often not noticed easily and there is a property that it is hard to predict the physical influence.

If it is general noise, you may get used to it. However, in many cases the low frequency sound deteriorates physical influences over time.

If there is insomnia or poor physical condition, low frequency sound may be the cause. Please check the presence and source of low frequency sound by using this app to solve your problems.

- 1/3 octave band analysis

- FFT analysis

- Report

In general, there are the following things that can be a source of low frequency sound.

- Sources at home: ventilation fan, refrigerator, air conditioner, blower, household fuel cell, heat pump water heater, dehydration pump, etc.

- Outdoor sources: automobiles, trains, aircraft, outdoor units for building air conditioning, factory noise, long-term vibration of road bridges, wind power generation, etc.

Sansho in the best season

Every year I look forward to the late spring season when the Japanese pepper, "Sansho" comes out.


I got some "Sansho" fruits from famous Wakayama Prefecture.


I used the fruits to make flavored oil, liqueur and pickling in salt.


Flavored oil is made by marinating them in extra virgin olive oil at a ratio of 1:3 to 1:4 by weight, and it takes about 5 days to finish.

It is best to finish marinating when it has a very refreshing citrus aroma. If the period of time is even a little longer, the pungency will become very strong.

This app can monitor the surrounding magnetic field in real time, it can be used for various purposes in real life.

For example, it can be used for investigation of static magnetic field, search for low electromagnetic field at alternating magnetic field (electromagnetic field), metal detection and more.

In the latest version, the alert sound function has been added.

High frequency noise

The emergency declaration was lifted all over Japan, and social activities are beginning to resume.

I was annoying the noise came in the back alley about 30 m away, it seemed the asphalt cutter that the pavement was being peeled off.

I moved to the window and measured it using the high frequency noise detection app, " Mosquitone Detector ".


In detection mode, the maximum noise level was 61.4 dB at 8-16 kHz, which was not so big level.


The noise level was even lower at 16-23kHz. This was because the amount of attenuation due to distance was more larger in the high frequency range.


In search mode, it was simply showing the direction of the window.

The construction work seemed to be completed in 20-30 minutes. The noise was annoying sound, so I was relieved to stop it in a short time.

COVID-19 activity restriction stress and noise problems.

With the COVID-19 pandemic, we spend a lot of time at home.
At the same time, it seems that noise troubles are occurring frequently. In Tokyo, the number of cases of noise disputes in March and April increased by nearly 30% compared to last year.

There is annoying noise around my house now. The renovation work in the neighborhood has resumed, and the noise is becoming extremely loud.


I felt noises as a fairly low frequency, so I investigated what kind of noise is present there by using " Low Frequency Detector " app.

As a result, many low frequency noises were clearly detected in the frequency range of 20Hz to 110Hz.

I will keep this noise data as evidence to prepare for future problems.
