Aw wi kin yɛri? Di wɔnda we di yes de mek ɛn di joyn we di sawnd de waka (Mechanism of Hearing) .

Yu dɔn ɛva stɔp ɛn tink bɔt aw di siŋ dɛn we wi kin lisin to ɛvride, di wɔd dɛn we wi kin tɔk to wi padi dɛn, di swit sawnd dɛn we bɔd dɛn kin mek, ɛn ɔda tin dɛn, kin kam insay wi yes ɛn wi bren kin ɔndastand dɛn? Na tru tru wan wɔndaful, kɔmpleks prɔses. I tan lɛk majik! So, tide wi go tɔk bɔt aw wi prɛshɔ yes dɛn de wok, insay wan rili simpul we, lɛk fɔ tɛl yu padi.

Di big wok we di smɔl ɔgan we dɛn kɔl di yes de du

Wi yes kin sheb to tri men pat, jɔs lɛk di rum dɛn na os. Dɛn na:

1. Ɔta Iya

2. Midul Iya

3. Insay Iya

Ɛni wan pan dɛn pat ya gɛt wan patikyula wok, as sawnd de travul go na wi bren. Lɛ wi si aw dat kin apin.

1. Ɔta Iya: Getway fɔ sawnd

We yu tink bɔt di yes, wetin kin kam na yu maynd fɔs na di pat we yu kin si na do? Na dat wi kin kɔl di pinna (dɛn kin kɔl am na mɛrɛsin `(Pinna)`). Di shep fɔ dis pinna dɛn mek am prɛsishɔn fɔ gɛda sawnd wev dɛn frɔm di envayrɔmɛnt ɛn dayrɛkt dɛn insay di yes. I tan lɛk se yu de gɛda signal frɔm wan `Satellite Dish`.

Imajin, we yu de tɔk to yu padi, di sawnd wev dɛn we yu de mek de travul na di ays ɛn nak di pɔsin we de lisin ɛn gɛda in yes.

Dɔn di sawnd wev dɛn we di ia drɔm kin gɛda kin travul tru wan smɔl tin we tan lɛk tiub we dɛn kɔl di ia kanal . di sawnd de travul along dis tכb to di biginin fכ di midul ia. Di kanal we de na di ia gɛt smɔl smɔl tin dɛn we tan lɛk ia ɛn gland dɛn we de mek di ia waks. Dɛn tin ya de protɛkt di yes frɔm dɔst, smɔl smɔl bɔd dɛn, ɛn ɔda tin dɛn.

2. Midul Iya: Usay dɛn de amplify sawnd

na di εnd pan di כditory tכb na wan rili dilik, tכn mεmbran de. na di ia dכm (כ `Tympanic Membrane`) we wi כl no. I tan lɛk drɔm in skin. We sawnd wev dɛn we kɔmɔt na do nak dis ia drɔm, i kin bigin fɔ shek .

Naw di rial wok bigin. Tri pan di smɔl smɔl bon dɛn we de na wi bɔdi de atak dis ia drɔm. Dɛn rili smɔl, bɔt dɛn de du big wok. dεn kin kכl dεn tri bon dεm ya `(Ossicles)`. Dɛn nem dɛn na:

• Malleus - Dis na lεk hama, we dεn tay pan di ia dכm.
• inkus - dis na di bon we de na di midul, we kכnekt to di ia dכm εn di כrikl.
• Stapes - Dis na di bon we smɔl pas ɔl na di bɔdi. I shep lɛk ɔs shuz.

we di ia dram de shek, di vaybshכn de fכs travul go na di osikul dεm, dεn go na di step dεm, εn leta go na di כrikl. dis tri bon dεm kכnekt to dεn wan dεm, dεn de wok lεk sכmכl lev sistεm, we de mek di vaybrεshכn dεm we de kכmכt frכm di ia dכm.Dɛn kin sɛn am to di insay yes. dis amplifyushכn rili imכtant, biכs di insay yes gεt wan wata. Fɔ mek di vaybreshɔn we de kam tru di briz go pas tru wan wata, dɛn fɔ strɔng.

Wan ɔda tin de we rili impɔtant na di midul yes. Dat na di Yustachian Tiub . Dis na jɔs wan smɔl tiub we gɛt kɔnekshɔn to di bak pat na wi trot. Yu dɔn ɛva fil lɛk se yu yes de ring we yu de klaym mawnten ɔ flay insay plen, dɔn yu wek wantɛm wantɛm wit wan strenj ‘klik’ sawnd? Na dat dis Yustachian tiub de du da tɛm de. We wi opin wi mɔt ɛn swɛla, dis tiub de opin ɛn lɔk fɔ mek di briz prɛshɔn na di tu say dɛn na di ia drɔm ikwal. Na da tɛm de di ia drɔm kin shek fri wan ɛn fayn fayn wan.

3. Insay Iya: Usay dɛn kin chenj sawnd to ilɛktrik signal

di step dεm, we de na di εnd pan di midul yes, de kכnekt to wan sכmכl כgan na di insay yes we lεk snεl sεl. Dɛn kɔl am di kɔklia . Insay de, wan spɛshal wata de ɛn bɔku bɔku tin dɛn we rili fayn ɛn we tan lɛk ia we dɛn kɔl ia sɛl .

we di amplified vaybreshכn wev dεm (`Vibrations`) frכm di midul ia pas tru di fכs we de insay di kכklia, dεn ia sεl dεm de stimulate. Jɔs lɛk we wef pas na wata, plant dɛn we de na di wata kin muf. we dεn ia sεl dεm ya de muv, wan amazing tin de apin: dat mεkanikal vaybrεshכn (`Mεkanikal Vaybrεshכn`) de bi ilektrikal signal dεm (`Electrical Signals` כ `Nerve Impulses`)!

di ia sεl dεm we de insay di kכklia rili spεshal. Dɛn kin gɛt difrɛn lɔng dɛn, lɛk di ki dɛn we de na piano. Jɔs lɛk aw ɛni ki de mek difrɛn sawnd, na so dɛn ia sɛl dɛn ya kin sɛnsitiv bak to difrɛn frɛkuɛns. Dat min se wan grup de ansa to ay-pitch sawnd (lɛk chirping sawnd) ɛn ɔda grup de ansa low-pitch sawnd (lɛk drɔm sawnd). Yu nɔ tink se dis dizayn rili wɔndaful?

apat frכm di yεri, di insay yes gεt bak wan pat we de kכntro wi bεlε (di `Vestibular System`). Bɔt bikɔs wi de tɔk bɔt fɔ yɛri tide, wi go tɔk bɔt dat ditayli leta.

Di joyn we sawnd de waka to di bren ɛn aw fɔ ɔndastand am

Naw di impɔtant pat de kam. di ilektrikal signal dεm we dεn ia sεl dεm de mek de go dayrekt to wi bren tru wan spεshal nεv we dεn k כl `Auditory Nerve` . di bren gεt spεshal sεntr we dεn de dεdiket fכ yεri (di `Auditory Cortex`).

Di bren de analayz dɛn ilɛktrik signal dɛn ya we de kam ɛn gi wi di ebul fɔ ɔndastand tin dɛn lɛk, ‘O, dis na mi mama in vɔys,’ ‘Dis na mi fav siŋ,’ ‘Dɔg de bark na do, a nɔ no if sɔntin nɔ rayt.’ Imajin, ɔl dis kin apin insay lɛs pas sɔm sɛkɔn, insay rili shɔt tɛm!

Nɔto dat nɔmɔ, bikɔs wi gɛt tu yes, di bren kin ebul fɔ no bak us say sawnd de kɔmɔt. Na in de sho if di sawnd de yɛri lawd smɔl ɔ saf smɔl na wan yes.

Wetin mek i rili impɔtant fɔ lɛ wi yɛri?

Dis nɔto sɔntin we strenj fɔ tɔk.

• Kɔmyunikeshɔn: Wi kin tɔk to ɔda pipul dɛn ɛn ɔndastand wetin dɛn de tɔk bay we wi de lisin.
• Fɔ lan: I impɔtant fɔ lisin we yu de lan nyu tin, ilɛksɛf na skul ɔ na wokples.
• Ɛnjɔy: Fɔ lisin to fayn fayn siŋ de mek yu gladi, ɛnjɔy di dayalɔg na fim, ɛn fɔ mek yusɛf kol bay we yu de lisin to di swit swit sawnd dɛn we di nature de mek (bɔd dɛn de siŋ, wata we de fɔdɔm) na ɔltin bɔt fɔ lisin.
• Sefty: We wi yɛri di sawnd we motoka de kam nia we wi de na rod, wi kin sev frɔm aksidɛnt, ɛn if faya de na wi os, dɛn kin wɔn wi wit di sawnd we di ``Faya Alam`` de mek. Fɔ ɔl dis, fɔ mek wi yes dɛn wok fayn fayn wan rili impɔtant.

Aw fɔ tek kia ɔf yu yes?

Wi nid fɔ kia fɔ wi yes dɛn we rili valyu ɛn we kɔmpleks, nɔto so? If wi tek kia ɔf di smɔl smɔl tin dɛn, wi go ebul fɔ mek wi yɛri fayn fɔ lɔng tɛm.

• Nɔ mek lawd nɔys: I nɔ fayn fɔ lisin to myuzik wit ay vɔlyum ɔ fɔ lisin to ɛdfɔn wit maksimal vɔlyum fɔ lɔng tɛm . If yu de wok na say dɛn we nɔys bɔku, lɛk faktri ɔ kɔnstrɔkshɔn sayt, wɛr tin fɔ protɛkt yu yes. Bikɔs if wi de na lawd nɔys fɔ lɔng tɛm, dat kin pwɛl di fayn fayn ia sɛl dɛn we wi bin tɔk bɔt, ɛn dis kin mek wi nɔ yɛri fayn sote go.
• Nɔ put tin dɛn na yu yes: Nɔ put tin dɛn we shap lɛk stik, kɔtɔn bɔd, ki, ɔ pin insay yu yes fɔ klin am. If yu du dat, i kin push di ia waks mɔ ɛn pwɛl di ia kanal ɔ di ia drɔm. Bɔku tɛm, iawaks kin kɔmɔt fɔ insɛf. If yu gɛt siriɔs diskɔmfɔt ɔ yu fil lɛk se yu yes dɔn blok, go to dɔktɔ fɔ advays.
• Kip yu yes dray: Sɔm pipul kin gɛt infɛkshɔn (e.g., Otitis Externa ɔ Swimmer’s Ear) if wata go insay dɛn yes we dɛn de was ɔ swim. I bɛtɛ fɔ lɛ dɛn kayn pipul dɛn de yuz di tin dɛn we dɛn kin yuz fɔ mek dɛn yes. Afta yu dɔn was, was di yes ɛn di ɔda pat we de rawnd di yes jisnɔ ɛn kip am dray.
• Yu fɔ no bɔt infɛkshɔn na yu yes: If yu gɛt yu yes we de at, wata we de kɔmɔt na yu yes, yu nɔ de yɛri fayn, yu de ring ɔltɛm na yu yes (`tinnitus`), ɔ yu gɛt diziz, nɔ ignore dɛn. Si dɔktɔ wantɛm wantɛm ɛn gɛt tritmɛnt. Sɔm midul ia infɛkshɔn (`Otitis Media`) kin siriɔs if dɛn nɔ trit am fayn.
• Di rayt mɛdikal chɛk-ap: Sɔm mɛdikal kɔndishɔn lɛk Dayabitis ɛn Haypatɛnshɔn kin afɛkt di we aw pɔsin de yɛri. Dɔn bak, sɔm mɛrɛsin dɛn (Ototoxic drugs) kin ambɔg di yes. So, if yu gɛt dɛn kayn mɛrɛsin ya, kɔntrol di rayt we ɛn fala wetin yu dɔktɔ tɛl yu fɔ du.

Fɔ sɔmtin (Tek-Home Message) .

Okay, so wi don tok plenti tide, no bi so? Fɔ tɔk am simpul wan, wi yes na wan ɔgan we rili kɔmpleks ɛn we de wok fayn fayn wan.

di sawnd wev dεm na di כta ia de kכlekt am, di midul ia de amplify am, kכnvכlt to ilektrikal signal dεm na di insay yes, εn i de transmit to di bren tru di כditory nεv. Dis na aw wi kin no, ɛnjɔy, ɛn ɔndastand di difrɛn sawnd dɛn na dis wɔl.

Sɔntɛm yu dɔn ɔndastand naw aw dis wɔndaful tin we wi ebul fɔ du gɛt valyu to wi na layf. So, tek kia ɔf yu yes ɛn protɛkt am. Bikɔs, fɔ yɛri gud gud wan rili impɔtant fɔ mek yu gɛt wɛlbɔdi, gladi at. If yu gɛt ɛni ɔda kwɛstyɔn bɔt dis, nɔ ɛva fred fɔ tɔk to dɔktɔ.
