(124)This big one was newly developed
(125)It’s safe. Let’s leave him alone
(126)When I went into the newly developed styrofoam
(127)I can only hear the banging sound from afar
(128)If we use this soundproof material, we can reduce noise between floors
(129)But even though it’s made by an affiliate of a large company
(130)The same affiliate didn’t use this product either
(131)The reason why it’s not fully developed is because
(132)Of course
(133)The government says we only need to use this
(134)There’s no reason to use new technology
(135)Let’s decide and give him some
(136)Why do we have to take responsibility for the problem
(137)Let’s leave him alone
(138)The government will take responsibility for this
(139)In an apartment built since the 2000s
(140)It’s made of 012cm thin styrofoam
(141)So we can’t stop the noise between floors With this
(142)In order to supplement the cushioning material for the 2cm weaving at an affiliate of a large company, the effect of developing the cushioning material and conducting the test was very excellent
(143)far and wide
(144)Nevertheless, even the conglomerate in question says it’s okay not to use the product, but it’s legal if the additional payment country spends more money and makes a mistake in the more expensive buffer material
(145)Reasoning is fixed
(146)Not used
(147)I shouldn’t have had a reason to use it
(148)For the rest, in the second episode
(149)Since the 1990s, I have been building a lot of apartments and building them quickly, making noise between floors
(150)2 When the noise between floors was too severe, residents filed a lawsuit against the fines of construction companies for the noise between floors in 003 at the time
(151)32 Hit by a Bite by a Resident
(152)Then in 2004, the government changed the rules
(153)5 After that, noise between floors was further improved

(1)When companies and the Ministry of Land, Infrastructure and Transport were engaged in a war of nerves with the people over noise between floors
(2)Has anyone raised the issue of noise between floors on the side of the people
(3)There was a part that said no
(4)Let’s leave him alone because he’s picky
(5)Audit report
(6)- Operation of the noise reduction system between floors of apartments –
(7)2019 4th floor noise problem
(8)The auditor found it!
(9)Let’s give him some
(10)Audit Background and Purpose
(11)For the first time in 2019, it’s been almost 20 years
(12)Sbsfree
(13)1 Background and purpose of audit
(14)In April 2003, the Ministry of Land, Infrastructure and Transport revised the Presidential Decree of the Regulations on Housing Construction Standards, etc. and introduced the floor impact noise noise standard that should be observed when constructing a house. 20048
(15)Floor recognized by photographs for meeting noise standards from to February 2019
(16)When constructed, it is not necessary to check whether the apartment houses met the intermediate noise standards after the construction is completed, but the photo recognition system is in operation
(17)In this case, in the economic map, even if the apartment scheduled to move in is unknown that actually meets the noise standards between floors and does not meet the standards, even if it suffers from intermediate noise after moving in
(18)It is buried under the finishing material, so it is difficult to determine the cause of the occurrence
(19)The Board of Audit and Inspection looked into the noise problem between floors
(20)Sves Premium 2
(21)- Operation of Noise Reduction System in Apartment Buildings
(22)1 Audit and Purpose
(23)What I thought after reading this report is
(24)Sves Premium
(25)Kim Sa-kyung and Purpose
(26)Someone has uncovered a 20-year-old problem
(27)1 Watchdog and purpose
(28)I didn’t ask, but this person I’m thankful for
(29)1 Kim Si-kyung and purpose
(30)I think he suffered from the noise between floors
(31)The Ministry of Land, Infrastructure and Transport recognized it as a standard floor
(32)Let’s see if it’s right to block noise between floors
(33)That’s why I went in and hit him
(34)It’s an auditor
(35)In 2019, the Board of Audit and Inspection of Korea looked into the actual noise between floors
(36)The staff hit the floor with a machine with a strange tire on it, and the experimenter
(37)The rain seems to be a standard equipment for measuring noise DB between storage floors
(38)Let’s look at the results that we received at the time of approval before we hit
(39)Analysis of Floor Impact Sound Measurement Results in Public Apartments
(40)As a result of measuring the floor impact sound by the Korea Data Audit Office, based on the reconstruction grade classification, 1st grade 37db or less and 2nd grade 41db or less 3

(48)If it’s 1, it’s generation
(49)It was probably the same as when the Ministry of Land, Infrastructure and Transport gave permission to build the first model
(50)It’s okay if the government regulations level 4 are issued, so up to level 4 is eligible for judgment
(51)On the paper, if it wasn’t just the door
(52)But the result was
(53)As a result of the measurement of floor impact sound by the Board of Audit and Inspection of Korea, based on the reconstruction grade classification, Grade 1 37db or lower, Grade 1 41db or lower, Grade 3 45db or lower, Grade 4 49db or lower

(62)Almost half of them are out-of-pocket
(63)According to the reference standard, it is not allowed except for the revision of the wage exceeding the appropriate standard, but the litigation fee is not allowed
(64)I’m scared
(65)I followed the recipe in 2004, so there’s no problem
(66)The Board of Audit and Inspection got angry once
(67)Thank you, 1st Ppakdom
(68)The Board of Audit and Inspection said that other private apartments would be fine
(69)I looked at the man who had been promoted
(70)Analysis of Floor Impact Sound Measurement Results of Private Apartment Buildings
(71)As a result of the measurement of floor impact sound by the Board of Audit and Inspection of Korea, based on the reconstruction grade classification, the first grade 37db or less, the second grade 41db or less, the fourth grade 49db or less

(1)Let’s leave him alone because he’s picky
(2)The Ministry of Land, Infrastructure and Transport has lied for over 20 years
(3)Isn’t that too much

(30)Please do your work thoroughly so that you don’t leave it as it isCaution
(31)I’m telling the Minister of Land, Infrastructure and Transport this way
(32)The sales department needs to change its policy even after receiving a report on the problem of refining in advance or investigating it, as the system for non-performance of appeal measures has been identified at all stages, such as post-management of construction
(33)① A plan to improve the operation of the system by supplementing the current pre-recognition system, but to check the inter-floor noise blocking performance even after construction, and Korea Land and Housing Corporation and Korea Construction
(34)I’m going to supervise the floor impact sound certification, etc
