Elektroninės triukšmo ausinės su belaidžio ryšio moduliu naudojant „Bluetooth“ (YT-74626)

ELECTRONIC EARNINGS WITH BLUETOOTH
Product description
The ear-muffs YT-74626 with a wireless communication module using bluetooth technology. They enable pairing with most smartphones, tablets, some laptops and other devices equipped with bluetooth technology. Four functional buttons on the side of one of the bowls allow, among other things, to adjust the volume, answer and end a call or change to the next music track. The ear cups can also be connected to some smartphones using the included jack cable. Thanks to the built-in AUX port and two directional microphones with noise reduction, it is possible to make phone calls or listen to music also via a cable.

TECHNICAL DATA

suppression efficiency: SNR 29 dB
maximum talk time: 8 hours
charging time: 3.5 hours
Lithium-polymer (Li-Po) battery with a capacity of 750mAh enables operation also at low temperatures and is characterized by high mechanical strength
weight: about 350 grams
WORK COMFORT

large and wide pillows spread the pressure over a larger area of the head and do not put pressure on the auricles
flat, adjustable headband with a width of 35 mm with a flexible support distribute the pressure over a larger surface of the head, which makes the headband almost imperceptible even after several hours of work
Pillow dimensions:

dimension A: approx. 35 mm
dimension B: approx. 70 mm
Pillow dimension

ADDITIONAL INFORMATION

audible and visual low battery alarm
micro USB charging port with red / green led indicator
50 cm long USB charging cable
3.5mm AUX port
3.5 mm jack cable with a length of 110 cm
the knob is used to adjust the volume when connected via a cable, in the case of a wireless connection, the volume is adjusted with the function buttons on one of the ear cups
APPLICATION EXAMPLES

The YT-74626 earmuffs in combination with a smartphone enable comfortable listening to music while working in conditions of excessive noise, and can also be used as a headset for making phone calls. All kinds of noise, e.g. in workshops with machining, in carpentry shops or production halls, is reduced by as much as 29dB.
HOW TO CHOOSE EARPHONES FOR THE WORKPLACE:

Protective and noise-reducing earmuffs protect the operator against harmful noise by lowering the sound level measured in decibels by the value of the SNR parameter. The upper limit for an 8-hour working day is set at 85 dB. If the average noise measurements at the workplace exceed this value, then you should have ear muffs with the SNR parameter that will allow the noise level to be reduced to 85 dB or less. Assuming that we will work all the time in ear muffs with the SNR 29 parameter and being in a working environment with a noise level of 113 dB, then we will reduce the noise to 84 dB.

If the operator wears the earmuffs for longer than a dozen or so minutes, then it is worth paying more attention to the structural elements improving the comfort of wearing them. Sufficiently wide sealing cushions made of skin-friendly materials should fit the entire auricle of the user. The soft headband cushion will ease the pressure on the top of the head. On the other hand, the force with which the earmuffs adhere to the head affects not only comfort, but also the effectiveness of damping, so for continuous operation, it is worth choosing earmuffs with not necessarily the highest available, but appropriately selected SNR parameter.
