September 29, 2017 (Fri) B point .. On the site boundary.
To say that there is a kindergarten in the neighborhood is to be exposed to such noise.
8: 00 ~ 17: 54. Lp period 1 s. A characteristics. LA 5 = 62.2 dB, Leq = 56.2 dB above data from the upper graph data (8: 00: 00 to 17: 54: 21)
How many times this noise regulation standard value of 50 dB (50.5 dB out)? 62.2 - 50.5 = 11.7 dB = 14.8 times for LA 5, 56.2 - 50.5 = 5.7 dB = 3.7 times for Leq .
How many times the noise is on holiday on weekdays?
2017/01/15 (holiday) When compared with the data of 8: 00 ~ 18: 00
The magnification of LA 5 is 62.2 - 45.5 = 16.7 dB = 46.8 times "46.8 times"
The magnification of Leq is 56.2 - 41.1 = 15.1 dB = 32.4 times The noise volume of 32.4 times the holiday on weekday
The data of 2016/12/11 (Sunday) is LA 5 = 45.9 dB (34.7% of 50.5 dB), Leq = 43.0 dB (19.1% of 50.5 dB).
Compared to 2016/12 / 11 (Sunday), 2017/9/29 is 42.7 times larger than LA 5 because it is 16.3 dB difference, Leq is 13.2 dB difference, so it is 20.9 times.
If you add the above 2017/01/23 minutes into the table, it will look like the following.
How many times the noise is on holiday on weekdays? (10 hours from 08: 00-18: 00)
magnification 2017/01 / 15 (Sun) 2016 / Dec. 11 (Sun) LA 5 Leq LA 5 Leq 2017/01/23 (Monday) 61.7 times 45.2 times 56.2 times 29.5 times 2017/09/29 (Friday) 46.8 times 32.4 times 42.7 times 20.9 times
Kindergarten noise is a noise that has a high degree of discomfort in the sound range for human beings and how to occur, so it is supposed to be evaluated at LA 5. On weekdays with kindergarten it will be 42 to 61 times more noisy.
It seems to have reported to the municipalities that they had taken noise countermeasures over several million yen in 2016 after municipalities have been instructed to reduce noise more than 20 times, but even after measures against noise, this is a reality.
Noise values of 45 to 61 times of January 23 , 2017 go to the main page .
Leq is a volume value used for noise evaluation of equipment that produces constant sound such as engine and air conditioner sound.
LA 5 is a volume value used for noise evaluation such as kindergarten noise.
The noise regulation standard value of 50 dB in this area means that up to 50 dB (50.4999 ...) of LA 5 value is safe when evaluating nursery school / kindergarten noise.
LA 5 is the 5% value from the top of the data group. Since the sound level meter measures the noise in μs, assuming that the measurement cycle is one minute, it means that it is a numerical value of 5% from the tens of thousands of data groups.
JIS standard of Lp. Excerpt: bottom
If the noise value is over even for a moment, that noise is a noise regulation value violation. Seeking noise control for malicious kindergarten operators is a correct action to try to create a correct society.

About 11% of the video is fast-forwarded due to the recording device malfunctioning, and the time difference has come up between the audio and the video.
Recording start time is correct. The recording end time is correct.
When Lp, LA 5 and Leq are superimposed, it becomes as follows.
The data of LA 5, Leq of 20170929 is a data group in which the measurement cycle is 1 minute, measurement data from xx hour x x minutes 58 seconds to 1 minute later 57 seconds is stored with the name of measurement start time added. LA 5, Leq of the upper graph are the same from xx hour x x minutes 00 seconds
It is a graph using the numerical value of its start time (minute) up to 59 seconds.
(For example: LA 5, 0 07:00 at 08:00, Leq is a numeric value calculated by sound level meter from 08: 00: 58 second to 08: 01: 57 sec The data are 53.3 dB and 50.4 dB, respectively , It is a graph of 53.3 dB, 50.4 dB from 08: 00: 00 second to 08: 00: 59: It is only necessary to shift the graph value by 58 seconds without writing this, but make graph value It is troublesome to change Excel function ...)
LA 5 = 62.2 dB, Leq = 56.18 dB from 8: 00: 00 to 17: 54: 21

***************
As mentioned above, the voice of Children is ridiculously noisy. Nurseries and kindergartens are incredibly annoying facilities.
Neighborhood residents suffer from noise.
Koi's voice is annoying ... Nursery is "annoying facility"?

It is strange that opinions like the above will appear in the newspaper.
The mass media are eyes, ears and mouths for those who suffer from pollution.
I do not know if the purpose is to imprint the opinion above to the reader, but it is not good to become a spokesman for someone's opinion.
The Yomiuri Shimbun reported that the government hid the wind from the Fukuichi nuclear power plant during the nuclear accident and reported that a large number of survivors were hit in the metropolitan area, as domestic newspaper companies had hidden damage to nuclear power plant accidents caused by power It is a newspaper company that was doing solid news report on nuclear damage damage. CNN, BBC, CCTV and other TV stations all over the world reported how the radiation from Fukushima flowed over 23 hours of broadcasting every day 24 hours a day, how was it going to be, Japan TV and newspapers It was reported that only the Yomiuri Shimbun was wrong that he did not report such information at all.
In France, only Yomiuri reported that as a domestic newspaper company, France instructed French citizens to wait in the room closed the window before high concentration of radioactive clouds hit the metropolitan area.
"(Yomiuri Newspaper at 14:12 on March 15, 2011)
Embassy of France ... a call for self-control to go to their citizens
Fukushima nuclear power plant embassy in Japan received a series of accidents at the Fukushima Daiichi nuclear power plant in the morning of 15th, saying "Weak radiation can reach Tokyo in about 10 hours" to the citizens who stay in Tokyo Recommendation to refrain from going out, and further, "I will not panic and close the window of my house."
Prior to this, the embassy had asked the French citizens to leave Tokyo immediately, as there was a danger of a strong aftershock occurrence in eastern Japan.
According to the British Paper Financial Times, France is the first to issue a recommendation to evacuate from Tokyo.
Even in other countries, there is an increasing trend towards asking their citizens to refrain from unnecessary urgent travel to Japan.
The US State Department announced its recommendation to its citizens on 13th, urged to refrain from urgent travel to Japan due to problems such as water shortages, food shortage, transportation, communication.
He told government officials who had no urgent duties to stop visiting Japan.
For Americans staying in Japan, the US embassy in Japan urged "to follow the instructions of the Japanese security authorities".
The Korean Ministry of Foreign Affairs and Trade also advised the Japanese government to refrain from traveling to Japan. "
At this time, radioactivity exceeding the standard was detected from tap water , distributed pet water, and the air used for manufacturing baby milk for infants was high radiation, so there was a fussy milk recovery.
Although opinion as a newspaper company may have changed, I want you to continue the attitude which becomes the eyes, ears and mouth of the suffering people.
*****
This kindergarten may be lacking ethics and moral ideas because it is family-run.
From the nursery school of a big company nearby, you can not hear the big noises like here.
I would like you to exclude malicious traders as an infant education industry.
