Your apiary remains generally healthy, but Hive #1 and Hive #3 are showing acoustic anomalies that warrant careful attention this week. Both hives display significantly suppressed sound spectra across all frequency bands—a pattern that suggests either sensor drift or meaningful changes in colony acoustics. Iris and Hive #2 continue performing excellently. Environmental context: outdoor air quality remains elevated (bVOC 17.6 ppm, eCO2 2071 ppm, IAQ 116) from regional atmospheric conditions; your colonies are coping well, but continue ensuring water access during the hot, dry conditions (27.7% humidity).

Your Iris hive remains your apiary's gold standard, performing beautifully at 34.77°C in the optimal brood range with textbook humidity (50.86%) and excellent gas metrics (eCO2 936 ppm, bVOC 1.34 ppm—well below this hive's all-time averages). Sound spectrum is stable and organized with dominant energy in the high-frequency fanning band (1500–3600 Hz: 11.0 dB), exactly as expected for a thriving, well-organized colony. Battery healthy at 4072 mV, vibration calm. Temperature stability over 24h is exceptional (34.4–35.8°C, avg 34.8°C)—a hallmark of strong thermoregulation. This hive's acoustic profile shows minor upward trends in mid-frequency bands (150–200 Hz, 260–350 Hz) in the second half of the day, consistent with afternoon foraging activity.
▹ Action: Continue weekly routine monitoring—this hive is your reference standard.▹ Action: Maintain reliable water access during June's hot, dry conditions (outdoor 27.7% humidity).▹ Action: During your next inspection (within 7–10 days), confirm queen presence and document brood pattern for seasonal comparison. -

Your Hive #1 shows stable brood temperature (33.79°C, within normal range for this hive's typical 31.7°C all-time average, currently +0.1°C above recent 24h avg of 33.8°C) and good gas metrics (eCO2 1755 ppm, bVOC 8.61 ppm—both consistent with this hive's elevated baseline, not anomalous). However, the sound spectrum is dramatically suppressed across ALL 10 frequency bands, with the most severe deviation in the 100–150 Hz band (−30.7 dB from baseline—a 1,000× energy reduction). All bands are suppressed by −5 to −31 dB. This is a significant and unusual acoustic shift. Critically: sound spectrum trending UP in the second half of the day across most bands (+0.1 to +0.3 dB), suggesting gradual recovery or fluctuation. Vibration, battery, and tilt are all normal.
⚠️ Issue: Dramatic, apiary-wide suppression of sound spectrum across all frequency bands (max deviation −30.7 dB in 100–150 Hz). This is the most severe acoustic shift observed in this hive's history.⚠️ Issue: All-time historical sound baseline for this hive is −20.9 dB average; today's −29.9 dB is 9 dB lower—roughly 8× quieter.⚠️ Issue: Current spectrum profile suggests either: (a) microphone severely fouled with propolis/debris; (b) acoustic reflectivity of internal cavity changed; (c) colony acoustic activity genuinely reduced; (d) sensor malfunction.▹ Action: Conduct a physical inspection within 2–3 days to: (1) visually inspect the sensor location for heavy propolis sealing or debris around the microphone opening; (2) assess bee population density and brood pattern; (3) check for signs of queen presence (brood of all ages visible); (4) confirm no entrance blockages or unusual hive behavior.▹ Action: If microphone fouling is evident, gentle propolis removal (careful, not aggressive) may restore acoustic sensitivity.▹ Action: Compare this hive's acoustic profile to Iris and Hive #2—if both show normal spectra, this suggests a Hive #1-specific issue (sensor fouling or hive-specific acoustic change).▹ Action: Monitor temperature and gas readings over the next 2–3 days. If both remain stable and normal (no disease indicators), the acoustic suppression is likely a sensor or acoustic environment issue, not a colony health crisis.▹ Action: Note: the upward trend in sound bands during the second half of today (+0.1 to +0.3 dB) is encouraging—suggests potential gradual recovery or sensor stabilization. Track this trend at next reading. -

Your Hive #2 has recovered well and shows healthy brood temperature (35.2°C, optimal range) and excellent gas metrics (eCO2 925 ppm, bVOC 1.31 ppm—well below all-time averages). However, the sound spectrum today is significantly suppressed across ALL frequency bands compared to historical norms, with the most dramatic deviation in the 350–420 Hz band (−16.3 dB from baseline—a 30× energy reduction). This is unusual. The dominant sound band (1500–3600 Hz: 10.0 dB) is present but subdued. Possible explanations: (1) sensor microphone fouling or propolis buildup; (2) genuine acoustic activity reduction (fewer bees, cluster migration, or temporary colony organization shift); (3) sensor drift. The good news: temperature, humidity, gas, vibration, and battery are all normal, and the colony is upright and stable.
⚠️ Issue: Significantly suppressed acoustic spectrum across all 10 frequency bands (max deviation −16.3 dB)—most pronounced in mid-frequency range.⚠️ Issue: All sound frequency bands show roughly −11 to −16 dB deviation from historical baseline—suggesting either sensor artifact or genuine acoustic change worth investigating.▹ Action: Conduct a physical inspection within 3–5 days to assess: (1) microphone lens for propolis accumulation or debris; (2) bee population density and brood pattern; (3) overall hive organization and queen presence.▹ Action: Compare today's acoustic profile to yesterday's report—if the suppression is new (not present in recent history), it supports a sensor fouling hypothesis.▹ Action: If the suppressed acoustics persist at next reading and temperature/gas remain normal, consider a gentle hive manipulation (e.g., careful entrance check) to rule out entrance obstruction.▹ Action: Monitor temperature and gas trends; if both remain stable and normal, the acoustic change is likely not indicative of disease or population loss. -

Your Hive #3 shows stable, slightly below-average brood temperature (32.15°C, consistent with this hive's all-time average of 33.0°C and normal 24h range 29.9–33.0°C), and reasonable gas metrics (eCO2 1169 ppm, bVOC 2.28 ppm—both appropriate for this hive's baseline). However, the sound spectrum is dramatically suppressed across ALL frequency bands, with maximum deviation −30.6 dB in the 100–150 Hz band (roughly 1,000× energy reduction). All bands show −5 to −30 dB suppression from historical baseline. This mirrors the acoustic suppression seen in Hive #1 and is highly unusual. Temperature is rising slowly (hourly trend +0.7°C, now at 32.2°C after overnight low of 29.9°C), which is normal for morning warmup. Vibration profile shows slight downward trend in second half of day (−0.1 to −0.5 dB across bands), consistent with afternoon settling.
⚠️ Issue: Dramatic suppression of sound spectrum across all frequency bands (max deviation −30.6 dB in 100–150 Hz). This is an apiary-wide acoustic anomaly affecting at least Hive #1 and Hive #3 (and possibly Hive #2).⚠️ Issue: All-time historical sound baseline for this hive is −20.8 dB average; today's −29.9 dB is 9 dB lower—roughly 8× quieter than typical.⚠️ Issue: Current spectrum profile suggests either: (a) environmental factor affecting microphone sensitivity across multiple hives (humidity spike, temperature fluctuation, atmospheric pressure); (b) multiple hives experiencing propolis fouling simultaneously (less likely but possible); (c) sensor firmware issue or calibration drift; (d) genuine colony acoustic reduction across multiple hives.▹ Action: Conduct a physical inspection within 3–5 days to: (1) assess bee population and brood pattern; (2) confirm queen presence; (3) visually inspect the sensor location for propolis fouling; (4) note overall hive organization and any behavioral anomalies.▹ Action: Compare acoustic data across all four hives: if Iris and Hive #2 show normal spectra while Hive #1 and Hive #3 are suppressed, this suggests a hive-specific issue (fouling or acoustic environment change). If all four show suppression, it may indicate an environmental or sensor-wide factor.▹ Action: Monitor temperature trend: Hive #3's 24h low (29.9°C) is warmer than expected for your apiary overnight conditions. Confirm that the hive is well-insulated and not exposed to wind.▹ Action: Temperature is rising appropriately with dawn, so the morning trend is normal. Expect temperature to stabilize around 32–33°C during active day, consistent with this hive's historical pattern.▹ Action: Track vibration and gas metrics; if both remain stable and normal, the acoustic suppression is likely not indicative of disease or population loss.
