Ka halulu pila. He aha ka mea e nānā ai ke kūʻai?

Hiki i ke kani kani ke hoʻopilikia i nā mea hoʻokele hoʻomanawanui, ʻoi aku hoʻi ma nā huakaʻi lōʻihi i ka wikiwiki ma mua o 100 km/h. He aha ke kumu o ka walaʻau a me ka mea e nānā ai ke kūʻai?

ʻOkoʻa kēlā me kēia pāpaʻi, loaʻa nā ʻano like ʻole, nā noi, a me nā mea ʻē aʻe. ʻAʻole kēia e pili ana i ka hoʻokaʻawale ʻana i nā kaila i ka hoʻoilo, ke kauwela, nā kau āpau, nā haʻuki a i ʻole nā ​​​​alanui, akā e pili ana i nā ʻokoʻa i loko o hoʻokahi ʻano. ʻO kēlā me kēia huila, ʻo ka nui like, ka laulā a me ka wikiwiki, loaʻa kahi alapine kūlohelohe ʻokoʻa. 'Ōlelo i ka alapine (frequency) i haalulu loa ia, no ka laʻana, ma muli o ke kaʻa ʻana ma nā ʻaoʻao alanui ʻole, a pēlā aku.

Ke kokoke ka pinepine o ka huila i ke alapine maoli o ke kaʻa, lilo kēia hopena i ʻoi aku ka maikaʻi a me ka leʻaleʻa. No laila, ʻo ka hoʻohālikelike ʻana i nā kaʻa a me ka hoʻohana ʻana i nā manaʻo o nā mea hoʻokele ʻē aʻe ʻaʻole i kūpono i nā manawa a pau, no ka mea, ʻo ke ʻano hoʻohālike like ʻole ma kahi kaʻa e hōʻike i ka hana leo maikaʻi, akā ma kahi kaʻa ʻē aʻe ʻaʻole ia e ʻae ʻia. ʻAʻole kēia ka hewa o ka mea hana kaʻa a i ʻole kahi kīnā o ke kaʻa, akā ʻo ke alapine like o ke kaʻa a me ka huila i ʻōlelo ʻia ma luna.

ʻO kēia kekahi o nā kumu e hana ai nā mea hana kaʻa kaʻa i nā hiʻohiʻona i hoʻolālā ʻia no nā kaʻa kikoʻī. ʻAʻole kēia he kaʻina hana kūʻai wale nō, akā ʻo ka hopena o ka hui pū ʻana a me ke koho ʻana i nā kaila no nā kumu he nui. ʻOiaʻiʻo, i kekahi manawa ke hāʻawi aku nei nā mea hana i ka hōʻoluʻolu acoustic i ka wā e hana ai i nā kaila e hoʻomaikaʻi ai i ka hoʻopaʻa ʻana, ka huki ʻana ma nā alanui pulu, ma waho o ke alanui, etc.

ʻO ka walaʻau ka walaʻau, akā no hea mai ia? ʻO ka mea e mahalo ai, ʻaʻole i pili wale ka ʻili a me ke kūʻē ʻana o ke alanui, akā, e ka ea pū kekahi, ka huila ponoʻī, ke ʻano hehi, ke kiʻekiʻe o ka hehi, a pēlā aku. Hoʻopilikia pū ʻia ka walaʻau e ka ea i hoʻopaʻa ʻia i loko o nā ʻāwī hehi, e hoʻoulu ai i ka resonance ʻelua i loko o ka ʻupena, nā haʻalulu o ka ea i hoʻonui ʻia ma ka hope o ka huila, a me ka haunaele i ke kahe ʻana ma waena o ka pio huila a me ka huila. ʻOiaʻiʻo, ʻo ka haʻahaʻa haʻahaʻa e loaʻa ai ka hopena maikaʻi ʻole i ka walaʻau i hana ʻia, akā ʻo kēia ka mālama ʻole ʻana o ka mea hoʻokele, ʻaʻole nā ​​hiʻohiʻona o kahi kaʻa.

ʻO nā panaka leo - pehea ka ʻokoʻa?

ʻO ka manaʻo, ʻoi aku ka maikaʻi o ke kaila ma ke ʻano o ka hoʻopaʻa ʻana, ʻoi aku ka maikaʻi o ka pae o ka hōʻoluʻolu a me ka walaʻau. ʻO nā kaila me nā ʻaoʻao ākea, nui a liʻiliʻi e emi ka ʻoluʻolu a me ka noisier. Hiki i nā pilikia o kēia ʻano ke lilo i hiʻohiʻona o nā kaila me kahi helu haʻahaʻa kiʻekiʻe, no laila inā ʻaʻole pono kēia, ʻoi aku ka maikaʻi o ka hoʻopukapuka ʻana i ia hopena.

Inā ʻoi aku ka maikaʻi o ka hana i makemake ʻia, ʻoi aku ka maikaʻi o ka hoʻokele ʻana a me ka moʻomeheu hana, ʻoi aku ka maikaʻi o nā kaila me kahi kiʻekiʻe kiʻekiʻe, ʻoi aku ka liʻiliʻi a me ka liʻiliʻi. ʻOiaʻiʻo, alakaʻi kēia i ka hōʻino ʻana i ka hana hoʻokele, ʻo ia hoʻi. nā ʻōwili, swaying, instability nui ma nā kihi, maikaʻi ʻole ka paʻa i ka wā braking a me ka wikiwiki, etc.

Hoʻemi ʻia nā pae walaʻau e nā hiʻohiʻona e like me ka hehi kuhikuhi me ka ʻole o nā wahi i hoʻopaʻa ʻia, a me nā ʻano ʻāpana hehi me nā hoʻonohonoho like ʻole a asymmetric. Eia kekahi, pono e hoʻolohe i nā grooves transverse, i hana ʻia i ke ʻano o ko lākou komo ʻana a me ko lākou puka ʻana ʻaʻole i kūlike me ka lihi tangential o ka hehi. Makemake ʻia ka palupalu kiʻekiʻe o ka hui ʻōpala, akā ʻo kēia, ma ka huli ʻana, hiki ke alakaʻi i ka ʻaʻahu ʻoi aku ka wikiwiki.

I ka hihia o nā kaʻa hoʻoilo, ʻaʻole hiki ke ʻike ʻia nā ʻano i luna, ʻoi aku ka maikaʻi o ka hele ʻana i ke ʻano hehi, akā ʻo nā hoʻonā hou i kēia manawa, ʻoi aku ka kiʻekiʻe o ka walaʻau i hana ʻia e nā kaʻa hoʻoilo ma mua o ke kumukūʻai hoʻohālikelike o ke kauwela. ka laulā a me nā ʻāpana like no ka laulā, ka nui, etc.

ʻO ka lepili Tire ma ke ʻano he kumu ʻike?

Ke koho ʻana i nā kaila, e ʻike ʻoe i nā lepili kūikawā i hoʻopili ʻia e nā mea hana a me nā mea kūʻai aku, kahi i hōʻike ʻia ai ka nui o nā ʻike waiwai i nā kiʻi. Hāʻawi ia i ka ʻike e pili ana i ke kūpaʻa ʻōwili (papa ikehu), ka paʻa pulu a me nā pae walaʻau.

- Ke kūpaʻa ʻana (ka papa ikehu a i ʻole ka pono wahie)

Hōʻike kēia ʻike i ka mea kūʻai aku i ka nui o ke kūpaʻa ʻōwili i ka hopena o ka hoʻokele wahie o ke kaʻa. Mai A a G. ʻO ka pae A ka hopena maikaʻi loa a ʻo ia hoʻi, ʻo ke kaʻa ʻana me ia mau kaʻa kaʻa kaiapuni a me ka waiwai.

Paʻa pulu

I kēia hihia, loiloi ʻia ka paʻa pulu i ka wā o ka braking. ʻO AF ka pālākiō helu, kahi ʻo A ka helu maikaʻi loa no ka mamao kū pōkole loa. ʻO ka mea maʻamau, ʻo kahi kaʻa kaʻa me ka pae kiʻekiʻe o ka ʻōwili kūʻē ʻana he haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa a me ka hope, ʻoiai aia kekahi mau hiʻohiʻona he kiʻekiʻe ka helu A a i ʻole B.

– Ka walaʻau ʻana o waho

Hōʻailona ʻia ka helu hope e ka leo leo me ka nui o nā nalu mai 1 a 3 a me kahi helu e hōʻike ana i nā decibels. ʻO ka mea nui ka helu decibels - ʻoiaʻiʻo, ʻo ka haʻahaʻa ka maikaʻi. I ka hapanui o nā hihia, ʻoi aku kēia waiwai ma mua o 70 dB, ʻoiai aia nā hiʻohiʻona me nā pae walaʻau a hiki i 65 dB.

ʻO ka palena hope ma ka lepili e pili ana i ka pae walaʻau i hoʻopuka ʻia e ka huila ʻōwili ma waho o ke kaʻa. ʻOiai e maopopo ana ka waiwai decibel i nā mea a pau, e hōʻike pū ana ka lepili i kahi hōʻailona leo hawewe ʻekolu. Hoʻokahi nalu ma kahi o 3 decibel ma lalo o ka pae kiʻekiʻe loa i ʻae ʻia ma ka European Union, ʻo ia hoʻi. ma kahi o 72 dB. Aia kekahi ʻokoʻa nui ma waena o 65 dB a me 72 dB? He ʻokoʻa nā manaʻo a he mea maʻamau loa ia, no laila pono e loaʻa i kāu ʻike ponoʻī iā ʻoe iho.
