Klasick\u00fd bicyklov\u00fd zvon\u010dek sa za posledn\u00fdch sto rokov takmer nezmenil. Mesto okolo teba v\u0161ak \u00e1no. Viac \u00e1ut, viac \u013eud\u00ed, viac hluku a najm\u00e4 viac sl\u00fachadiel, ktor\u00e9 \u0165a dok\u00e1\u017eu \u00faplne odreza\u0165 od reality. Pr\u00e1ve na tento probl\u00e9m zareagovala automobilka \u0160koda Auto,<\/a> ktor\u00e1 predstavila netradi\u010dn\u00e9 rie\u0161enie, zvon\u010dek, ktor\u00fd dok\u00e1\u017ee \u201eprekri\u010da\u0165\u201c aj modern\u00e9 technol\u00f3gie potl\u00e1\u010dania hluku.<\/p>\n

Novinka dostala n\u00e1zov DuoBell a vznikla v spolupr\u00e1ci s vedcami z University of Salford. Technol\u00f3gia zvon\u010deka predstavuje v\u00fdsledok v\u00fdskumu, ktor\u00fd sa zameral na konkr\u00e9tny probl\u00e9m, pre\u010do dnes chodci \u010dasto nereaguj\u00fa ani na klasick\u00e9 zvonenie.<\/p>\n

D\u00f4vod je, \u017ee st\u00e1le viac \u013eud\u00ed nos\u00ed sl\u00fachadl\u00e1 s akt\u00edvnym potl\u00e1\u010dan\u00edm hluku<\/a>. Tieto zariadenia analyzuj\u00fa okolit\u00fd zvuk a vytv\u00e1raj\u00fa \u201eproti-zvuk\u201c, ktor\u00fd ho ru\u0161\u00ed. ANC technol\u00f3gia je z\u00e1chrancom po\u010das dlhej cesty vlakom, no na chodn\u00edku vytvor\u00ed \u010dastokr\u00e1t rizikov\u00e9 situ\u00e1cie.<\/p>\n

V Lond\u00fdne nos\u00ed tak\u00e9to sl\u00fachadl\u00e1 pod\u013ea odhadov a\u017e polovica chodcov. Z\u00e1rove\u0148 tam prudko rastie po\u010det cyklistov a s t\u00fdm aj po\u010det kol\u00edzi\u00ed. Len v roku 2024 ich pribudlo o 24 %. Kombin\u00e1cia nepozornosti a technol\u00f3gie vytvorila situ\u00e1ciu, ktor\u00fa klasick\u00fd zvon\u010dek u\u017e nezvl\u00e1dne. DuoBell sa sna\u017e\u00ed tento probl\u00e9m ob\u00eds\u0165, nie porazi\u0165 silou. Namiesto hlasnej\u0161ieho zvuku vyu\u017e\u00edva slabinu samotn\u00fdch algoritmov.<\/p>\n

Vedci po\u010das testov identifikovali \u00fazke frekven\u010dn\u00e9 p\u00e1smo, ktor\u00e9 syst\u00e9my ANC nedok\u00e1\u017eu efekt\u00edvne filtrova\u0165. Ide o rozsah pribli\u017ene 750 a\u017e 780 Hz. Pr\u00e1ve na t\u00fato frekvenciu naladili nov\u00fd zvon\u010dek. Preladi\u0165 frekvencie samo o sebe nesta\u010d\u00ed, preto\u00a0DuoBell obsahuje aj druh\u00fd rezon\u00e1tor, ktor\u00fd prid\u00e1va vy\u0161\u0161ie t\u00f3ny, a \u0161peci\u00e1lny mechanizmus \u00faderov. Ten nevytv\u00e1ra pravideln\u00e9 \u201ecinknutie\u201c, ale r\u00fdchle a nepravideln\u00e9 zvuky. Pre algoritmus ide o probl\u00e9m, nestihne ich spracova\u0165 a potla\u010di\u0165. Ke\u010f cyklista zazvon\u00ed, zvuk prenikne aj cez kvalitn\u00e9 sl\u00fachadl\u00e1.<\/p>\n

Zauj\u00edmav\u00e9 je, \u017ee cel\u00e9 rie\u0161enie zostalo mechanick\u00e9. DuoBell teda nepotrebuje \u017eiadnu elektroniku, ani \u017eiadne bat\u00e9rie.\u00a0<\/p>\n

Testy uk\u00e1zali, \u017ee zvon\u010dek DuoBell skuto\u010dne funguje. Chodci so zapnut\u00fdm ANC<\/a> z\u00edskali a\u017e o 22 metrov v\u00e4\u010d\u0161iu reak\u010dn\u00fa vzdialenos\u0165. To je rozdiel medzi tesn\u00fdm stretom a bezpe\u010dn\u00fdm vyhnut\u00edm sa.<\/p>\n

\u201eBicyklov\u00e9 zvon\u010deky sa viac ne\u017e sto rokov nezmenili, ale svet okolo nich \u00e1no,\u201c povedal Edwards: \u201eAj mal\u00e1 \u00faprava m\u00f4\u017ee v\u00fdrazne zlep\u0161i\u0165 bezpe\u010dnos\u0165 v mest\u00e1ch.\u201c<\/p>\n

Do v\u00fdvoja sa zapojili aj \u010fal\u0161ie firmy a agent\u00fary vr\u00e1tane PHD a produk\u010dnej spolo\u010dnosti Unit9. Prototypy<\/a> n\u00e1sledne testovali priamo v uliciach Lond\u00fdna, kde ich pou\u017e\u00edvali kuri\u00e9ri zo slu\u017eby Deliveroo. Mnoh\u00ed si chceli zvon\u010dek po skon\u010den\u00ed testovania necha\u0165.<\/p>\n

Spolo\u010dnos\u0165 nezaost\u00e1va ani v dizajne zvon\u010deka. DuoBell nadviazal na aktu\u00e1lny \u0161t\u00fdl zna\u010dky \u0160koda, vr\u00e1tane materi\u00e1lov a povrchovej \u00fapravy. Nejde teda len o funk\u010dn\u00fd doplnok, ale aj o produkt, ktor\u00fd zapadne do modern\u00e9ho bicykla. Za zmienku stoj\u00ed ur\u010dite aj to, \u017ee \u0160koda pl\u00e1nuje zverejni\u0165 v\u00fdsledky v\u00fdskumu, aby sa o nich mohli opiera\u0165 \u010fal\u0161\u00ed odborn\u00edci. Nejde teda len o jeden zvon\u010dek, ale o snahu otvori\u0165 diskusiu o bezpe\u010dnosti<\/a> v mest\u00e1ch. Mo\u017eno u\u017e o p\u00e1r rokov sa tak\u00e9to zvon\u010deky stan\u00fa normou.<\/p>\n
