ACOUSTIC CONSULTANCY – THE IMPORTANCE OF NOISE CONTROL
At AF Acoustics, we provide a wide array of acoustic consultancy services. We take a professional approach to sound and conduct services such as noise and sound proofing consultancy.
In addition to this, we offer building air tests as well as sound insulation testing and other acoustic assessments. In this short article, we will cover noise control and explain why it is important within the construction industry.
WHAT IS NOISE CONTROL?
Noise control, by definition, is a set of strategies enforced with the aim to reduce the impact of sound and noise pollution. There are many ways in which noise control can be conducted. The methods used solely depend on the building environment itself.
For example, a print company may require soundproofing in order to reduce the leakage of sound outside of normal working hours. Another example could be a restaurant environment with a loud extractor fan. This restaurant may require a newer fan replacement in order to reduce noise pollution or an acoustic enclosure specified. All environments must be appropriately assessed to compile a suitable noise reduction strategy with AF Acoustics sound insulation testing.
NIOSH, who are the American National Institute for Occupational Safety, suggest a hierarchical approach to noise control. This hierarchy is essentially broken in five tiers. The highest tier being the most effective and the lowest being the least effective.
In order of the least effective to the most effective, the five tiers are – PPE, Administrative Controls, Engineering Controls, Substitution and Elimination
This refers to the complete removal of the sound hazard. This is the most effective form of noise control whenever applicable.
Substitution of sound is the second most effective method of noise control. This strategy consists of identifying noisy components and later replacing them with a quieter alternatives. For example, a loud generator may be replaced with a newer quieter model in order to reduce noise pollution.
This is the third most effective tier and consists of making changes to machinery, equipment or processes. For example, existing equipment can be modified to include noise absorbing material to help reduce the impact of sound.
Administrative controls are the second least effective method of reducing the impact of sound. This strategy consists of administrational changes such as reducing the length of time that workers are exposed to sound. It can also mean signposting to notify nearby people that an area may be exposed to loud sounds during set times. This allows them to remove themselves from the location or equip themselves with PPE for added protection.
The use of PPE, otherwise known as personal protective equipment, is the least effective method of noise control according to NIOSH. This strategy involves equipping workers or people nearby with sound protective equipment, such as ear plugs or ear defenders.
WHY IS NOISE CONTROL IMPORTANT?
Noise control is extremely important as exposure to constant sound or loud noises can have negative effects on our health. Damage to the ears can occur when we are exposed to ongoing loud noises. Hearing loss can be prevented with noise control methods.
Noise induced hearing loss can result in expensive compensation claims and an increase in insurance costs. In addition to that, noise pollution can cause stress, fatigue and also disrupt learning as well as communication.
In an environment such as a restaurant, noise pollution can be extremely unpleasant for customers. This can deter customers from wanting to return and therefore can affect profits.
Contact AF Acoustics About Noise Control
Noise pollution can be very devastating to both business and our health. This is why we stress the importance of effective noise control. In the construction industry, standards must be met to reduce noise pollution through structural sound insulation and/or other noise control methods.

ACOUSTICAL KUSHAWIKI <unk> MAHASIRI YA KUDhibiti kelele Katika AF Acoustics, tunatoa huduma mbalimbali za ushauri wa sauti. Sisi kuchukua mbinu ya kitaalamu kwa sauti na kuendesha huduma kama vile kelele na sauti proofing ushauri. Kwa kuongezea hii, tunatoa majaribio ya hewa ya jengo pamoja na majaribio ya kutenganisha sauti na tathmini zingine za sauti. Katika makala hii fupi, tutazungumzia udhibiti wa kelele na kueleza kwa nini ni muhimu ndani ya sekta ya ujenzi. Kudhibiti Kelele Ni Nini? Kudhibiti kelele, kwa ufafanuzi, ni seti ya mikakati kutekelezwa kwa lengo la kupunguza athari ya kelele na uchafuzi wa kelele. Kuna njia nyingi ambazo udhibiti wa kelele unaweza kufanywa. Mbinu zinazotumiwa hutegemea tu mazingira ya jengo lenyewe. Kwa mfano, kampuni ya uchapishaji inaweza kuhitaji soundproofing ili kupunguza uvujaji wa sauti nje ya saa za kawaida za kazi. Mfano mwingine unaweza kuwa mazingira ya mgahawa na mashabiki wa uchimbaji wa sauti. Mlo huu unaweza kuhitaji kubadilisha kipepeo kipya ili kupunguza uchafuzi wa kelele au kifuniko cha sauti kilichoainishwa. Kwa hivyo, kwa sababu ya hali ya hewa, ni muhimu kuamua jinsi ya kupunguza kelele kwa kutumia njia ya AF Acoustics. NIOSH (American National Institute for Occupational Safety) ni shirika la kimataifa linalohusika katika kutunza mazingira ya kazi na usalama wa kazi. Utaratibu huo wa cheo umegawanywa katika ngazi tano. Kiwango cha juu kuwa na ufanisi zaidi na ya chini kuwa na ufanisi mdogo. Katika utaratibu wa chini ya ufanisi kwa ufanisi zaidi, ngazi tano ni <unk> PPE, Udhibiti wa Usimamizi, Udhibiti wa Uhandisi, Uingizwaji na Uondoaji Hii inahusu kuondolewa kabisa kwa hatari ya sauti. Hii ni aina yenye ufanisi zaidi ya udhibiti wa kelele wakati wowote inapatikana. Kubadilisha sauti ni njia ya pili yenye matokeo zaidi ya kudhibiti kelele. Mkakati huu unajumuisha kutambua vipengele vyenye kelele na baadaye kuzibadilisha na mbadala zenye ukimya. Kwa mfano, jenereta yenye kelele nyingi yaweza kubadilishwa na jenereta mpya yenye ukimya ili kupunguza uchafuzi wa kelele. Hii ni ngazi ya tatu yenye ufanisi zaidi na inajumuisha kufanya mabadiliko kwa mashine, vifaa au michakato. Kwa mfano, vifaa vilivyopo vinaweza kubadilishwa ili viingize vifaa vya kunyonya kelele ili kusaidia kupunguza athari za sauti. Udhibiti wa kiutawala ni njia ya pili isiyo na ufanisi wa kupunguza athari ya sauti. Mkakati huu unajumuisha mabadiliko ya kiutawala kama vile kupunguza muda ambao wafanyakazi wanafunuliwa kwa sauti. Pia inaweza kumaanisha kuweka ishara za kuwahubiria watu walio karibu kwamba eneo fulani laweza kusikilizwa kwa sauti kubwa wakati fulani. Hii inawawezesha kujiondoa kutoka mahali hapo au kujiandaa na PPE kwa ulinzi wa ziada. Matumizi ya vifaa vya kujilinda binafsi (PPE) ni njia bora zaidi ya kudhibiti kelele. Mfumo huu unahusisha kuwapa wafanyakazi au watu walio karibu vifaa vya kulinda sauti, kama vile vifuniko vya masikio au watetezi wa masikio. Kwa Nini Kudhibiti Kelele Ni Muhimu? Kudhibiti kelele ni muhimu sana kama mfiduo wa sauti ya mara kwa mara au kelele kubwa inaweza kuwa na athari mbaya kwa afya yetu. Masikio yanaweza kuharibiwa tunapokuwa na kelele nyingi. Kupoteza uwezo wa kusikia kwaweza kuzuiwa kwa kutumia mbinu za kudhibiti kelele. Kupoteza kusikia kunakofanywa na kelele kunaweza kusababisha madai ya fidia ya gharama kubwa na ongezeko la gharama za bima. Kwa kuongezea, uchafuzi wa kelele unaweza kusababisha mkazo, uchovu na pia kuvuruga kujifunza na mawasiliano. Katika mazingira kama vile mgahawa, uchafuzi wa kelele unaweza kuwa mbaya sana kwa wateja. Hii inaweza kuzuia wateja kutoka kutaka kurudi na kwa hiyo inaweza kuathiri faida. Kwa sababu ya hali ya hewa, uchafuzi wa kelele unaweza kuwa mbaya sana kwa biashara na afya yetu. Hii ndiyo sababu tunasisitiza umuhimu wa udhibiti mzuri wa kelele. Katika sekta ya ujenzi, viwango lazima kukidhi ili kupunguza uchafuzi wa kelele kwa njia ya insulation ya sauti ya muundo na / au mbinu nyingine za kudhibiti kelele. Kama wewe ni kuangalia kwa ajili ya kudhibiti kelele ufanisi, kuwasiliana na sisi leo ili kugundua jinsi tunaweza kusaidia. Uchunguzi wa Kisa Ulioonyeshwa
