Ua hoʻopuka ʻo Iapana i nā alakaʻi no ia mau mea hoʻolaha i Ianuali 2010 a ua ʻae ʻia e ka US i ke kānāwai i Dekemaba 2010. Ua hoʻopuka ka US National Highway Traffic Safety Administration i kāna ʻōlelo hoʻoholo hope loa i Pepeluali 2018, a koi i ka hāmeʻa e hoʻopuka i nā leo ʻōlelo aʻo i ka wā e holo ana me ka wikiwiki ma lalo o 18.6 mph. (30 km/h) me ka hoʻokō ʻana ma ka mahina ʻo Kepakemapa 2020, akā ʻo 50% o nā kaʻa "noho mālie" pono e loaʻa nā leo ʻōlelo aʻo ma mua o Kepakemapa 2019. Ma ʻApelila 2014, ua ʻae ka European Parliament i ke kānāwai e koi ana i ka hoʻohana pono ʻana i kahi Acoustic Vehicle Alerting System ( AVAS).Pono nā mea hana e hoʻokomo i kahi ʻōnaehana AVAS i nā kaʻa uila ʻehā a me nā kaʻa uila hybrid i ʻae ʻia mai Iulai 1, 2019, a me nā kaʻa uila mālie a me nā kaʻa hybrid hou i hoʻopaʻa inoa ʻia mai Iulai 2021. dBA (ma loko o 2 mau mika) inā holo ke kaʻa i 20 km/h (12 mph) a ʻoi aku ka lohi, a ʻo ka lōʻihi he 75 dBA.
Ua hoʻomohala kekahi mau mea hana kaʻa kaʻa uila, a mai Dekemaba 2011 i loaʻa nā kaʻa ʻenehana kiʻekiʻe i ka mākeke me nā leo ʻōlelo aʻoaʻo uila i hana ʻia me ka Nissan Leaf, Chevrolet Volt, Honda FCX Clarity, Nissan Fuga Hybrid/Infiniti M35, Hyundai Sonata Hybrid, a ka Toyota Prius (Iapana wale nō).ʻO nā hiʻohiʻona i hoʻolako ʻia me nā ʻōnaehana hoʻāla ʻakomi ʻia ka BMW i3 2014 (ʻaʻole i loaʻa ke koho i ka US), Toyota Camry Hybrid 2012 makahiki, Lexus CT200h 2012, nā mana EV āpau o ka Honda Fit, a me nā kaʻa ʻohana Prius a pau i hoʻopuka hou ʻia ma United States. , me ka maʻamau 2012 kumu hoʻohālike makahiki Prius, ka Toyota Prius v, Prius c a me ka Toyota Prius Plug-in Hybrid.ʻO ka 2013 Smart uila uila, ke koho, hele mai me nā leo i hoʻāla ʻia i ka US a me Iapana a hoʻohana lima ʻia ma ʻEulopa.
ʻO Enhanced Vehicle Acoustics (EVA), kahi hui i hoʻokumu ʻia ma Silicon Valley, Kaleponi a hoʻokumu ʻia e nā haumāna Stanford ʻelua me ke kōkua o ke kālā hua mai ka National Federation of the Blind, i hoʻomohala i kahi ʻenehana ma hope o ka mākeke i kapa ʻia ʻo "Vehicular Operations Sound Emitting Systems" (VOSES). ).Hoʻohana ka mea hana i nā kaʻa uila hybrid e like me nā kaʻa ʻenekini puhi ahi maʻamau i ka wā e hele ai ke kaʻa i ke ʻano uila leo (EV mode), akā ma kahi hapa o ka pae kani o ka hapa nui o nā kaʻa.Ma ka wikiwiki ma waena o 20 mau mile i kēlā me kēia hola (32 km/h) a i 25 mau mile i kēlā me kēia hola (40 km/h) e pio ka ʻōnaehana kani.Paʻa pū ka ʻōnaehana i ka wā e hoʻoikaika ai ka ʻenekini puhi ahi.
Hoʻohana ʻo VOSES i nā leo leo liʻiliʻi liʻiliʻi i kau ʻia ma nā pūnāwai huila o ka hybrid a hoʻopuka i nā leo kikoʻī e pili ana i ke ala e neʻe ai ke kaʻa i mea e hōʻemi ai i ka pollution walaʻau a e hoʻonui i ka ʻike leo no ka poʻe hele wāwae.Inā e neʻe ana ke kaʻa i mua, ʻike ʻia nā leo ma ke ala i mua;a inā huli ke kaʻa i ka hema a ʻākau paha, hoʻololi ke kani ma ka hema a ʻākau paha.Ua ʻōlelo ka hui ʻo "ʻoi aku ka hoʻopiʻi ʻana o nā kani kani, nā beeps a me nā ʻōleʻa ma mua o ka pono", a ʻo nā leo maikaʻi loa no ka makaʻala ʻana i ka poʻe hele wāwae e like me ke kaʻa, e like me "ka puʻupuʻu palupalu o kahi ʻenekini a i ʻole ka lohi ʻana o nā kaʻa ma ka papahele."ʻO kekahi o nā ʻōnaehana kani waho o ka EVA i hoʻolālā ʻia no Toyota Prius.
